-FAQ
-===
-
-**Q: Where can I get help with pexpect?  Is there a mailing list?**
-
-A: You can use the `pexpect tag on Stackoverflow <http://stackoverflow.com/questions/tagged/pexpect>`__
-to ask questions specifically related to Pexpect. For more general Python
-support, there's the python-list_ mailing list, and the `#python`_
-IRC channel.  Please refrain from using github for general
-python or systems scripting support.
-
-.. _python-list: https://mail.python.org/mailman/listinfo/python-list
-.. _#python: https://www.python.org/community/irc/
-
-**Q: Why don't shell pipe and redirect (| and >) work when I spawn a command?**
-
-A: Remember that Pexpect does NOT interpret shell meta characters such as
-redirect, pipe, or wild cards (``>``, ``|``, or ``*``). That's done by a shell not
-the command you are spawning. This is a common mistake. If you want to run a
-command and pipe it through another command then you must also start a shell.
-For example::
-
-    child = pexpect.spawn('/bin/bash -c "ls -l | grep LOG > log_list.txt"')
-    child.expect(pexpect.EOF)
-
-The second form of spawn (where you pass a list of arguments) is useful in
-situations where you wish to spawn a command and pass it its own argument list.
-This can make syntax more clear. For example, the following is equivalent to the
-previous example::
-
-    shell_cmd = 'ls -l | grep LOG > log_list.txt'
-    child = pexpect.spawn('/bin/bash', ['-c', shell_cmd])
-    child.expect(pexpect.EOF)
-
-**Q: The `before` and `after` properties sound weird.**
-
-A: This is how the -B and -A options in grep works, so that made it
-easier for me to remember. Whatever makes my life easier is what's best.
-Originally I was going to model Pexpect after Expect, but then I found
-that I didn't actually like the way Expect did some things. It was more
-confusing. The `after` property can be a little confusing at first,
-because it will actually include the matched string. The `after` means
-after the point of match, not after the matched string.
-
-**Q: Why not just use Expect?**
-
-A: I love it. It's great. I has bailed me out of some real jams, but I
-wanted something that would do 90% of what I need from Expect; be 10% of
-the size; and allow me to write my code in Python instead of TCL.
-Pexpect is not nearly as big as Expect, but Pexpect does everything I
-have ever used Expect for.
-
-.. _whynotpipe:
-
-**Q: Why not just use a pipe (popen())?**
-
-A: A pipe works fine for getting the output to non-interactive programs.
-If you just want to get the output from ls, uname, or ping then this
-works. Pipes do not work very well for interactive programs and pipes
-will almost certainly fail for most applications that ask for passwords
-such as telnet, ftp, or ssh.
-
-There are two reasons for this.
-
-* First an application may bypass stdout and print directly to its
-  controlling TTY. Something like SSH will do this when it asks you for
-  a password. This is why you cannot redirect the password prompt because
-  it does not go through stdout or stderr.
-
-* The second reason is because most applications are built using the C
-  Standard IO Library (anything that uses ``#include <stdio.h>``). One
-  of the features of the stdio library is that it buffers all input and
-  output. Normally output is line buffered when a program is printing to
-  a TTY (your terminal screen). Everytime the program prints a line-feed
-  the currently buffered data will get printed to your screen. The
-  problem comes when you connect a pipe. The stdio library is smart and
-  can tell that it is printing to a pipe instead of a TTY. In that case
-  it switches from line buffer mode to block buffered. In this mode the
-  currently buffered data is flushed when the buffer is full. This
-  causes most interactive programs to deadlock. Block buffering is more
-  efficient when writing to disks and pipes. Take the situation where a
-  program prints a message ``"Enter your user name:\n"`` and then waits
-  for you type type something. In block buffered mode, the stdio library
-  will not put the message into the pipe even though a linefeed is
-  printed. The result is that you never receive the message, yet the
-  child application will sit and wait for you to type a response. Don't
-  confuse the stdio lib's buffer with the pipe's buffer. The pipe buffer
-  is another area that can cause problems. You could flush the input
-  side of a pipe, whereas you have no control over the stdio library buffer.
-
-More information: the Standard IO library has three states for a
-``FILE *``. These are: _IOFBF for block buffered; _IOLBF for line buffered;
-and _IONBF for unbuffered. The STDIO lib will use block buffering when
-talking to a block file descriptor such as a pipe. This is usually not
-helpful for interactive programs. Short of recompiling your program to
-include fflush() everywhere or recompiling a custom stdio library there
-is not much a controlling application can do about this if talking over
-a pipe.
-
-The program may have put data in its output that remains unflushed
-because the output buffer is not full; then the program will go and
-deadlock while waiting for input -- because you never send it any
-because you are still waiting for its output (still stuck in the STDIO's
-output buffer).
-
-The answer is to use a pseudo-tty. A TTY device will force line
-buffering (as opposed to block buffering). Line buffering means that you
-will get each line when the child program sends a line feed. This
-corresponds to the way most interactive programs operate -- send a line
-of output then wait for a line of input.
-
-I put "answer" in quotes because it's ugly solution and because there is
-no POSIX standard for pseudo-TTY devices (even though they have a TTY
-standard...). What would make more sense to me would be to have some way
-to set a mode on a file descriptor so that it will tell the STDIO to be
-line-buffered. I have investigated, and I don't think there is a way to
-set the buffered state of a child process. The STDIO Library does not
-maintain any external state in the kernel or whatnot, so I don't think
-there is any way for you to alter it. I'm not quite sure how this
-line-buffered/block-buffered state change happens internally in the
-STDIO library. I think the STDIO lib looks at the file descriptor and
-decides to change behavior based on whether it's a TTY or a block file
-(see isatty()).
-
-I hope that this qualifies as helpful. Don't use a pipe to control
-another application.
-
-**Q: Can I do screen scraping with this thing?**
-
-A: That depends. If your application just does line-oriented output then
-this is easy. If a program emits many terminal sequences, from video
-attributes to screen addressing, such as programs using curses, then
-it may become very difficult to ascertain what text is displayed on a screen.
-
-We suggest using the `pyte <https://github.com/selectel/pyte>`_ library to
-screen-scrape.  The module :mod:`pexpect.ANSI` released with previous versions
-of pexpect is now marked deprecated and may be removed in the future.
-
-**Q: I get strange behavior with pexect and gevent**
-
-A: Pexpect uses fork(2), exec(2), select(2), waitpid(2), and implements its
-own selector in expect family of calls. pexpect has been known to misbehave
-when paired with gevent.  A solution might be to isolate your pexpect
-dependent code from any frameworks that manipulate event selection behavior
-by running it in an another process entirely.

-Handling unicode
-````````````````
-
-By default, :class:`spawn` is a bytes interface: its read methods return bytes,
-and its write/send and expect methods expect bytes. If you pass the *encoding*
-parameter to the constructor, it will instead act as a unicode interface:
-strings you send will be encoded using that encoding, and bytes received will
-be decoded before returning them to you. In this mode, patterns for
-:meth:`~spawn.expect` and :meth:`~spawn.expect_exact` should also be unicode.
-
-.. versionchanged:: 4.0
-
-   :class:`spawn` provides both the bytes and unicode interfaces. In Pexpect
-   3.x, the unicode interface was provided by a separate ``spawnu`` class.
-
-For backwards compatibility, some Unicode is allowed in bytes mode: the
-send methods will encode arbitrary unicode as UTF-8 before sending it to the
-child process, and its expect methods can accept ascii-only unicode strings.
-
-.. note::
-
-   Unicode handling with pexpect works the same way on Python 2 and 3, despite
-   the difference in names. I.e.:
-
-   - Bytes mode works with ``str`` on Python 2, and :class:`bytes` on Python 3,
-   - Unicode mode works with ``unicode`` on Python 2, and :class:`str` on Python 3.

-Common problems
-===============
-
-Threads
--------
-
-On Linux (RH 8) you cannot spawn a child from a different thread and pass the
-handle back to a worker thread. The child is successfully spawned but you can't
-interact with it. The only way to make it work is to spawn and interact with the
-child all in the same thread. [Adam Kerrison]
-
-Timing issue with send() and sendline()
----------------------------------------
-
-This problem has been addressed and should not affect most users.
-
-It is sometimes possible to read an echo of the string sent with
-:meth:`~pexpect.spawn.send` and :meth:`~pexpect.spawn.sendline`. If you call
-:meth:`~pexpect.spawn.send` and then immediately call :meth:`~pexpect.spawn.readline`,
-you may get part of your output echoed back. You may read back what you just
-wrote even if the child application does not explicitly echo it. Timing is
-critical. This could be a security issue when talking to an application that
-asks for a password; otherwise, this does not seem like a big deal. But why do
-TTYs do this?
-
-People usually report this when they are trying to control SSH or some other
-login. For example, if your code looks something like this::
-
-    child.expect ('[pP]assword:')
-    child.sendline (my_password)
-
-
-1. SSH prints "password:" prompt to the user.
-2. SSH turns off echo on the TTY device.
-3. SSH waits for user to enter a password.
-
-When scripting with Pexpect what can happen is that Pexpect will respond to the
-"password:" prompt before SSH has had time to turn off TTY echo. In other words,
-Pexpect sends the password between steps 1. and 2., so the password gets echoed
-back to the TTY. I would call this an SSH bug.
-
-Pexpect now automatically adds a short delay before sending data to a child
-process. This more closely mimics what happens in the usual human-to-app
-interaction. The delay can be tuned with the ``delaybeforesend`` attribute of the
-spawn class. In general, this fixes the problem for everyone and so this should
-not be an issue for most users. For some applications you might with to turn it
-off::
-
-    child = pexpect.spawn ("ssh user@example.com")
-    child.delaybeforesend = None
-
-Truncated output just before child exits
-----------------------------------------
-
-So far I have seen this only on older versions of Apple's MacOS X. If the child
-application quits it may not flush its output buffer. This means that your
-Pexpect application will receive an EOF even though it should have received a
-little more data before the child died. This is not generally a problem when
-talking to interactive child applications. One example where it is a problem is
-when trying to read output from a program like *ls*. You may receive most of the
-directory listing, but the last few lines will get lost before you receive an EOF.
-The reason for this is that *ls* runs; completes its task; and then exits. The
-buffer is not flushed before exit so the last few lines are lost. The following
-example demonstrates the problem::
-
-    child = pexpect.spawn('ls -l')
-    child.expect(pexpect.EOF)
-    print child.before       
-
-Controlling SSH on Solaris
---------------------------
-
-Pexpect does not yet work perfectly on Solaris. One common problem is that SSH
-sometimes will not allow TTY password authentication. For example, you may
-expect SSH to ask you for a password using code like this::
-
-    child = pexpect.spawn('ssh user@example.com')
-    child.expect('password')
-    child.sendline('mypassword')
-
-You may see the following error come back from a spawned child SSH::
-
-    Permission denied (publickey,keyboard-interactive). 
-
-This means that SSH thinks it can't access the TTY to ask you for your password.
-The only solution I have found is to use public key authentication with SSH.
-This bypasses the need for a password. I'm not happy with this solution. The
-problem is due to poor support for Solaris Pseudo TTYs in the Python Standard
-Library.
-
-child does not receive full input, emits BEL
---------------------------------------------
-
-You may notice when running for example cat(1) or base64(1), when sending a
-very long input line, that it is not fully received, and the BEL ('\a') may
-be found in output.
-
-By default the child terminal matches the parent, which is often in "canonical
-mode processing". You may wish to disable this mode. The exact limit of a line
-varies by operating system, and details of disabling canonical mode may be
-found in the docstring of :meth:`~pexpect.spawn.send`.

-Examples
-========
-
-Under the distribution tarball directory you should find an "examples" directory.
-This is the best way to learn to use Pexpect. See the descriptions of Pexpect
-Examples.
-
-`topip.py <https://github.com/pexpect/pexpect/blob/master/examples/topip.py>`_
-  This runs `netstat` on a local or remote server. It calculates some simple
-  statistical information on the number of external inet connections. This can
-  be used to detect if one IP address is taking up an excessive number of
-  connections. It can also send an email alert if a given IP address exceeds a
-  threshold between runs of the script. This script can be used as a drop-in
-  Munin plugin or it can be used stand-alone from cron. I used this on a busy
-  web server that would sometimes get hit with denial of service attacks. This
-  made it easy to see if a script was opening many multiple connections. A
-  typical browser would open fewer than 10 connections at once. A script might
-  open over 100 simultaneous connections.
-
-`hive.py <https://github.com/pexpect/pexpect/blob/master/examples/hive.py>`_
-  This script creates SSH connections to a list of hosts that you provide.
-  Then you are given a command line prompt. Each shell command that you
-  enter is sent to all the hosts. The response from each host is collected
-  and printed. For example, you could connect to a dozen different
-  machines and reboot them all at once.
-
-`script.py <https://github.com/pexpect/pexpect/blob/master/examples/script.py>`_
-  This implements a command similar to the classic BSD "script" command.
-  This will start a subshell and log all input and output to a file.
-  This demonstrates the :meth:`~pexpect.spawn.interact` method of Pexpect.
-
-`ftp.py <https://github.com/pexpect/pexpect/blob/master/examples/ftp.py>`_
-  This demonstrates an FTP "bookmark". This connects to an ftp site;
-  does a few ftp tasks; and then gives the user interactive control over
-  the session. In this case the "bookmark" is to a directory on the
-  OpenBSD ftp server. It puts you in the i386 packages directory. You
-  can easily modify this for other sites. This demonstrates the
-  :meth:`~pexpect.spawn.interact` method of Pexpect.
-
-`monitor.py <https://github.com/pexpect/pexpect/blob/master/examples/monitor.py>`_
-  This runs a sequence of commands on a remote host using SSH. It runs a
-  simple system checks such as uptime and free to monitor the state of
-  the remote host.
-
-`passmass.py <https://github.com/pexpect/pexpect/blob/master/examples/passmass.py>`_
-  This will login to each given server and change the password of the
-  given user. This demonstrates scripting logins and passwords.
-
-`python.py <https://github.com/pexpect/pexpect/blob/master/examples/python.py>`_
-  This starts the python interpreter and prints the greeting message
-  backwards. It then gives the user iteractive control of Python. It's
-  pretty useless!
-
-`ssh_tunnel.py <https://github.com/pexpect/pexpect/blob/master/examples/ssh_tunnel.py>`_
-  This starts an SSH tunnel to a remote machine. It monitors the
-  connection and restarts the tunnel if it goes down.
-
-`uptime.py <https://github.com/pexpect/pexpect/blob/master/examples/uptime.py>`_
-  This will run the uptime command and parse the output into variables.
-  This demonstrates using a single regular expression to match the
-  output of a command and capturing different variable in match groups.
-  The grouping regular expression handles a wide variety of different
-  uptime formats.

-History
-=======
-
-Releases
---------
-
-Version 4.6
-```````````
-
-* The :meth:`.pxssh.login` method now supports an ``ssh_config`` parameter,
-  which can be used to specify a file path to an SSH config file
-  (:ghpull:`490`).
-* Improved compatability for the ``crlf`` parameter of :class:`~.PopenSpawn`
-  (:ghpull:`493`)
-* Fixed an issue in read timeout handling when using :class:`~.spawn` and
-  :class:`~.fdspawn` with the ``use_poll`` parameter (:ghpull:`492`).
-
-Version 4.5
-```````````
-
-* :class:`~.spawn` and :class:`~.fdspawn` now have a ``use_poll`` parameter.
-  If this is True, they will use :func:`select.poll` instead of :func:`select.select`.
-  ``poll()`` allows file descriptors above 1024, but it must be explicitly
-  enabled due to compatibility concerns (:ghpull:`474`).
-* The :meth:`.pxssh.login` method has several new and changed options:
-
-  * The option ``password_regex`` allows changing
-    the password prompt regex, for servers that include ``password:`` in a banner
-    before reaching a prompt (:ghpull:`468`).
-  * :meth:`~.pxssh.login` now allows for setting up SSH tunnels to be requested once
-    logged in to the remote server. This option is ``ssh_tunnels`` (:ghpull:`473`).
-    The structure should be like this::
-
-          {
-            'local': ['2424:localhost:22'],   # Local SSH tunnels
-            'remote': ['2525:localhost:22'],  # Remote SSH tunnels
-            'dynamic': [8888],                # Dynamic/SOCKS tunnels
-          }
-
-  * The option ``spawn_local_ssh=False`` allows subsequent logins from the
-    remote session and treats the session as if it was local (:ghpull:`472`).
-  * Setting ``sync_original_prompt=False`` will prevent changing the prompt to
-    something unique, in case the remote server is sensitive to new lines at login
-    (:ghpull:`468`).
-  * If ``ssh_key=True`` is passed, the SSH client forces forwarding the authentication
-    agent to the remote server instead of providing a key (:ghpull:`473`).
-
-Version 4.4
-```````````
-
-* :class:`~.PopenSpawn` now has a ``preexec_fn`` parameter, like :class:`~.spawn`
-  and :class:`subprocess.Popen`, for a function to be called in the child
-  process before executing the new command. Like in ``Popen``, this works only
-  in POSIX, and can cause issues if your application also uses threads
-  (:ghpull:`460`).
-* Significant performance improvements when processing large amounts of data
-  (:ghpull:`464`).
-* Ensure that ``spawn.closed`` gets set by :meth:`~.spawn.close`, and improve
-  an example for passing ``SIGWINCH`` through to a child process (:ghpull:`466`).
-
-Version 4.3.1
-`````````````
-
-* When launching bash for :mod:`pexpect.replwrap`, load the system ``bashrc``
-  from a couple of different common locations (:ghpull:`457`), and then unset
-  the ``PROMPT_COMMAND`` environment variable, which can interfere with the
-  prompt we're expecting (:ghpull:`459`).
-
-Version 4.3
-```````````
-
-* The ``async=`` parameter to integrate with asyncio has become ``async_=``
-  (:ghpull:`431`), as *async* is becoming a Python keyword from Python 3.6.
-  Pexpect will still recognise ``async`` as an alternative spelling.
-* Similarly, the module ``pexpect.async`` became ``pexpect._async``
-  (:ghpull:`450`). This module is not part of the public API.
-* Fix problems with asyncio objects closing file descriptors during garbage
-  collection (:ghissue:`347`, :ghpull:`376`).
-* Set the ``.pid`` attribute of a :class:`~.PopenSpawn` object (:ghpull:`417`).
-* Fix passing Windows paths to :class:`~.PopenSpawn` (:ghpull:`446`).
-* :class:`~.PopenSpawn` on Windows can pass string commands through to ``Popen``
-  without splitting them into a list (:ghpull:`447`).
-* Stop ``shlex`` trying to read from stdin when :class:`~.PopenSpawn` is
-  passed ``cmd=None`` (:ghissue:`433`, :ghpull:`434`).
-* Ensure that an error closing a Pexpect spawn object raises a Pexpect error,
-  rather than a Ptyprocess error (:ghissue:`383`, :ghpull:`386`).
-* Cleaned up invalid backslash escape sequences in strings (:ghpull:`430`,
-  :ghpull:`445`).
-* The pattern for a password prompt in :mod:`pexpect.pxssh` changed from
-  ``password`` to ``password:`` (:ghpull:`452`).
-* Correct docstring for using unicode with spawn (:ghpull:`395`).
-* Various other improvements to documentation.
-
-Version 4.2.1
-`````````````
-
-* Fix to allow running ``env`` in replwrap-ed bash.
-* Raise more informative exception from pxssh if it fails to connect.
-* Change ``passmass`` example to not log passwords entered.
-
-Version 4.2
-```````````
-
-* Change: When an ``env`` parameter is specified to the :class:`~.spawn` or
-  :class:`~.run` family of calls containing a value for ``PATH``, its value is
-  used to discover the target executable from a relative path, rather than the
-  current process's environment ``PATH``.  This mirrors the behavior of
-  :func:`subprocess.Popen` in the standard library (:ghissue:`348`).
-
-* Regression: Re-introduce capability for :meth:`read_nonblocking` in class
-  :class:`fdspawn` as previously supported in version 3.3 (:ghissue:`359`).
-
-Version 4.0
-```````````
-
-* Integration with :mod:`asyncio`: passing ``async=True`` to :meth:`~.spawn.expect`,
-  :meth:`~.spawn.expect_exact` or :meth:`~.spawn.expect_list` will make them return a
-  coroutine. You can get the result using ``yield from``, or wrap it in an
-  :class:`asyncio.Task`. This allows the event loop to do other things while
-  waiting for output that matches a pattern.
-* Experimental support for Windows (with some caveats)—see :ref:`windows`.
-* Enhancement: allow method as callbacks of argument ``events`` for
-  :func:`pexpect.run` (:ghissue:`176`).
-* It is now possible to call :meth:`~.spawn.wait` multiple times, or after a process
-  is already determined to be terminated without raising an exception
-  (:ghpull:`211`).
-* New :class:`pexpect.spawn` keyword argument, ``dimensions=(rows, columns)``
-  allows setting terminal screen dimensions before launching a program
-  (:ghissue:`122`).
-* Fix regression that prevented executable, but unreadable files from
-  being found when not specified by absolute path -- such as
-  /usr/bin/sudo (:ghissue:`104`).
-* Fixed regression when executing pexpect with some prior releases of
-  the multiprocessing module where stdin has been closed (:ghissue:`86`).
-
-Backwards incompatible changes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-* Deprecated ``pexpect.screen`` and ``pexpect.ANSI``. Please use other packages
-  such as `pyte <https://pypi.python.org/pypi/pyte>`__ to emulate a terminal.
-* Removed the independent top-level modules (``pxssh fdpexpect FSM screen ANSI``)
-  which were installed alongside Pexpect. These were moved into the Pexpect
-  package in 3.0, but the old names were left as aliases.
-* Child processes created by Pexpect no longer ignore SIGHUP by default: the
-  ``ignore_sighup`` parameter of :class:`pexpect.spawn` defaults to False. To
-  get the old behaviour, pass ``ignore_sighup=True``.
-
-Version 3.3
-```````````
-
-* Added a mechanism to wrap REPLs, or shells, in an object which can conveniently
-  be used to send commands and wait for the output (:mod:`pexpect.replwrap`).
-* Fixed issue where pexpect would attempt to execute a directory because
-  it has the 'execute' bit set (:ghissue:`37`).
-* Removed the ``pexpect.psh`` module. This was never documented, and we found
-  no evidence that people use it. The new :mod:`pexpect.replwrap` module
-  provides a more flexible alternative.
-* Fixed ``TypeError: got <type 'str'> ('\r\n') as pattern`` in :meth:`spawnu.readline`
-  method (:ghissue:`67`).
-* Fixed issue where EOF was not correctly detected in :meth:`~.interact`, causing
-  a repeating loop of output on Linux, and blocking before EOF on BSD and
-  Solaris (:ghissue:`49`).
-* Several Solaris (SmartOS) bugfixes, preventing :exc:`IOError` exceptions, especially
-  when used with cron(1) (:ghissue:`44`).
-* Added new keyword argument ``echo=True`` for :class:`spawn`.  On SVR4-like
-  systems, the method :meth:`~.isatty` will always return *False*: the child pty
-  does not appear as a terminal.  Therefore, :meth:`~.setecho`, :meth:`~.getwinsize`,
-  :meth:`~.setwinsize`, and :meth:`~.waitnoecho` are not supported on those platforms.
-
-After this, we intend to start working on a bigger refactoring of the code, to
-be released as Pexpect 4. There may be more bugfix 3.x releases, however.
-
-Version 3.2
-```````````
-
-* Fix exception handling from :func:`select.select` on Python 2 (:ghpull:`38`).
-  This was accidentally broken in the previous release when it was fixed for
-  Python 3.
-* Removed a workaround for ``TIOCSWINSZ`` on very old systems, which was causing
-  issues on some BSD systems (:ghpull:`40`).
-* Fixed an issue with exception handling in :mod:`~pexpect.pxssh` (:ghpull:`43`)
-
-The documentation for :mod:`~pexpect.pxssh` was improved.
-
-Version 3.1
-```````````
-
-* Fix an issue that prevented importing pexpect on Python 3 when ``sys.stdout``
-  was reassigned (:ghissue:`30`).
-* Improve prompt synchronisation in :mod:`~pexpect.pxssh` (:ghpull:`28`).
-* Fix pickling exception instances (:ghpull:`34`).
-* Fix handling exceptions from :func:`select.select` on Python 3 (:ghpull:`33`).
-
-The examples have also been cleaned up somewhat - this will continue in future
-releases.
-
-Version 3.0
-```````````
-
-The new major version number doesn't indicate any deliberate API incompatibility.
-We have endeavoured to avoid breaking existing APIs. However, pexpect is under
-new maintenance after a long dormancy, so some caution is warranted.
-
-* A new :ref:`unicode API <unicode>` was introduced.
-* Python 3 is now supported, using a single codebase.
-* Pexpect now requires at least Python 2.6 or 3.2.
-* The modules other than pexpect, such as :mod:`pexpect.fdpexpect` and
-  :mod:`pexpect.pxssh`, were moved into the pexpect package. For now, wrapper
-  modules are installed to the old locations for backwards compatibility (e.g.
-  ``import pxssh`` will still work), but these will be removed at some point in
-  the future.
-* Ignoring ``SIGHUP`` is now optional - thanks to Kimmo Parviainen-Jalanko for
-  the patch.
-
-We also now have `docs on ReadTheDocs <https://pexpect.readthedocs.io/>`_,
-and `continuous integration on Travis CI <https://travis-ci.org/pexpect/pexpect>`_.
-
-Version 2.4
-```````````
-
-* Fix a bug regarding making the pty the controlling terminal when the process
-  spawning it is not, actually, a terminal (such as from cron)
-
-Version 2.3
-```````````
-
-* Fixed OSError exception when a pexpect object is cleaned up. Previously, you
-  might have seen this exception::
-
-      Exception exceptions.OSError: (10, 'No child processes')
-      in <bound method spawn.__del__ of <pexpect.spawn instance at 0xd248c>> ignored
-
-  You should not see that anymore. Thanks to Michael Surette.
-* Added support for buffering reads. This greatly improves speed when trying to
-  match long output from a child process. When you create an instance of the spawn
-  object you can then set a buffer size. For now you MUST do the following to turn
-  on buffering -- it may be on by default in future version::
-
-      child = pexpect.spawn ('my_command')
-      child.maxread=1000 # Sets buffer to 1000 characters.
-
-* I made a subtle change to the way TIMEOUT and EOF exceptions behave.
-  Previously you could either expect these states in which case pexpect
-  will not raise an exception, or you could just let pexpect raise an
-  exception when these states were encountered. If you expected the
-  states then the ``before`` property was set to everything before the
-  state was encountered, but if you let pexpect raise the exception then
-  ``before`` was not set. Now, the ``before`` property will get set either
-  way you choose to handle these states.
-* The spawn object now provides iterators for a *file-like interface*.
-  This makes Pexpect a more complete file-like object. You can now write
-  code like this::
-
-      child = pexpect.spawn ('ls -l')
-      for line in child:
-          print line
-
-* write and writelines() no longer return a value. Use send() if you need that
-  functionality. I did this to make the Spawn object more closely match a
-  file-like object.
-* Added the attribute ``exitstatus``. This will give the exit code returned
-  by the child process. This will be set to ``None`` while the child is still
-  alive. When ``isalive()`` returns 0 then ``exitstatus`` will be set.
-* Made a few more tweaks to ``isalive()`` so that it will operate more
-  consistently on different platforms. Solaris is the most difficult to support.
-* You can now put ``TIMEOUT`` in a list of expected patterns. This is just like
-  putting ``EOF`` in the pattern list. Expecting for a ``TIMEOUT`` may not be
-  used as often as ``EOF``, but this makes Pexpect more consistent.
-* Thanks to a suggestion and sample code from Chad J. Schroeder I added the ability
-  for Pexpect to operate on a file descriptor that is already open. This means that
-  Pexpect can be used to control streams such as those from serial port devices. Now,
-  you just pass the integer file descriptor as the "command" when constructing a
-  spawn open. For example on a Linux box with a modem on ttyS1::
-
-      fd = os.open("/dev/ttyS1", os.O_RDWR|os.O_NONBLOCK|os.O_NOCTTY)
-      m = pexpect.spawn(fd) # Note integer fd is used instead of usual string.
-      m.send("+++") # Escape sequence
-      m.send("ATZ0\r") # Reset modem to profile 0
-      rval = m.expect(["OK", "ERROR"])
-
-* ``read()`` was renamed to ``read_nonblocking()``. Added new ``read()`` method
-  that matches file-like object interface. In general, you should not notice
-  the difference except that ``read()`` no longer allows you to directly set the
-  timeout value. I hope this will not effect any existing code. Switching to
-  ``read_nonblocking()`` should fix existing code.
-* Changed the name of ``set_echo()`` to ``setecho()``.
-* Changed the name of ``send_eof()`` to ``sendeof()``.
-* Modified ``kill()`` so that it checks to make sure the pid ``isalive()``.
-* modified ``spawn()`` (really called from ``__spawn()``) so that it does not
-  raise an exception if ``setwinsize()`` fails. Some platforms such as Cygwin
-  do not like setwinsize. This was a constant problem and since it is not a
-  critical feature I decided to just silence the error.  Normally I don't like
-  to do that, but in this case I'm making an exception.
-* Added a method ``close()`` that does what you think. It closes the file
-  descriptor of the child application. It makes no attempt to actually kill the
-  child or wait for its status.
-* Add variables ``__version__`` and ``__revision__`` (from cvs) to the pexpect
-  modules.  This is mainly helpful to me so that I can make sure that I'm testing
-  with the right version instead of one already installed.
-* ``log_open()`` and ``log_close(`` have been removed. Now use ``setlog()``.
-  The ``setlog()`` method takes a file object. This is far more flexible than
-  the previous log method. Each time data is written to the file object it will
-  be flushed. To turn logging off simply call ``setlog()`` with None.
-* renamed the ``isAlive()`` method to ``isalive()`` to match the more typical
-  naming style in Python. Also the technique used to detect child process
-  status has been drastically modified. Previously I did some funky stuff
-  with signals which caused indigestion in other Python modules on some
-  platforms. It was a big headache. It still is, but I think it works
-  better now.
-* attribute ``matched`` renamed to ``after``
-* new attribute ``match``
-* The ``expect_eof()`` method is gone. You can now simply use the
-  ``expect()`` method to look for EOF.
-* **Pexpect works on OS X**, but the nature of the quirks cause many of the
-  tests to fail. See bugs. (Incomplete Child Output). The problem is more
-  than minor, but Pexpect is still more than useful for most tasks.
-* **Solaris**: For some reason, the *second* time a pty file descriptor is created and
-  deleted it never gets returned for use. It does not effect the first time
-  or the third time or any time after that. It's only the second time. This
-  is weird... This could be a file descriptor leak, or it could be some
-  peculiarity of how Solaris recycles them. I thought it was a UNIX requirement
-  for the OS to give you the lowest available filedescriptor number. In any case,
-  this should not be a problem unless you create hundreds of pexpect instances...
-  It may also be a pty module bug.
-
-
-Moves and forks
----------------
-
-* Pexpect development used to be hosted on Sourceforge.
-* In 2011, Thomas Kluyver forked pexpect as 'pexpect-u', to support
-  Python 3. He later decided he had taken the wrong approach with this.
-* In 2012, Noah Spurrier, the original author of Pexpect, moved the
-  project to Github, but was still too busy to develop it much.
-* In 2013, Thomas Kluyver and Jeff Quast forked Pexpect again, intending
-  to call the new fork Pexpected. Noah Spurrier agreed to let them use
-  the name Pexpect, so Pexpect versions 3 and above are based on this
-  fork, which now lives `here on Github <https://github.com/pexpect/pexpect>`_.

-Pexpect makes Python a better tool for controlling other
-applications.
-
-Pexpect is a pure Python module for spawning child applications;
-controlling them; and responding to expected patterns in their output.
-Pexpect works like Don Libes' Expect. Pexpect allows your script to
-spawn a child application and control it as if a human were typing
-commands.
-
-Pexpect can be used for automating interactive applications such as
-ssh, ftp, passwd, telnet, etc. It can be used to a automate setup
-scripts for duplicating software package installations on different
-servers. It can be used for automated software testing. Pexpect is in
-the spirit of Don Libes' Expect, but Pexpect is pure Python. Unlike
-other Expect-like modules for Python, Pexpect does not require TCL or
-Expect nor does it require C extensions to be compiled. It should work
-on any platform that supports the standard Python pty module. The
-Pexpect interface was designed to be easy to use.

-API Overview
-============
-
-Pexpect can be used for automating interactive applications such as ssh, ftp,
-mencoder, passwd, etc. The Pexpect interface was designed to be easy to use.
-
-Here is an example of Pexpect in action::
-
-    # This connects to the openbsd ftp site and
-    # downloads the recursive directory listing.
-    import pexpect
-    child = pexpect.spawn('ftp ftp.openbsd.org')
-    child.expect('Name .*: ')
-    child.sendline('anonymous')
-    child.expect('Password:')
-    child.sendline('noah@example.com')
-    child.expect('ftp> ')
-    child.sendline('lcd /tmp')
-    child.expect('ftp> ')
-    child.sendline('cd pub/OpenBSD')
-    child.expect('ftp> ')
-    child.sendline('get README')
-    child.expect('ftp> ')
-    child.sendline('bye')
-
-Obviously you could write an ftp client using Python's own :mod:`ftplib` module,
-but this is just a demonstration. You can use this technique with any application.
-This is especially handy if you are writing automated test tools.
-
-There are two important methods in Pexpect -- :meth:`~pexpect.spawn.expect` and
-:meth:`~pexpect.spawn.send` (or :meth:`~pexpect.spawn.sendline` which is
-like :meth:`~pexpect.spawn.send` with a linefeed). The :meth:`~pexpect.spawn.expect`
-method waits for the child application to return a given string. The string you
-specify is a regular expression, so you can match complicated patterns. The
-:meth:`~pexpect.spawn.send` method writes a string to the child application.
-From the child's point of view it looks just like someone typed the text from a
-terminal. After each call to :meth:`~pexpect.spawn.expect` the ``before`` and ``after``
-properties will be set to the text printed by child application. The ``before``
-property will contain all text up to the expected string pattern. The ``after``
-string will contain the text that was matched by the expected pattern.
-The match property is set to the `re match object <http://docs.python.org/3/library/re#match-objects>`_.
-
-An example of Pexpect in action may make things more clear. This example uses
-ftp to login to the OpenBSD site; list files in a directory; and then pass
-interactive control of the ftp session to the human user::
-
-    import pexpect
-    child = pexpect.spawn ('ftp ftp.openbsd.org')
-    child.expect ('Name .*: ')
-    child.sendline ('anonymous')
-    child.expect ('Password:')
-    child.sendline ('noah@example.com')
-    child.expect ('ftp> ')
-    child.sendline ('ls /pub/OpenBSD/')
-    child.expect ('ftp> ')
-    print child.before   # Print the result of the ls command.
-    child.interact()     # Give control of the child to the user.
-
-Special EOF and TIMEOUT patterns
---------------------------------
-
-There are two special patterns to match the End Of File (:class:`~pexpect.EOF`)
-or a Timeout condition (:class:`~pexpect.TIMEOUT`). You can pass these
-patterns to :meth:`~pexpect.spawn.expect`. These patterns are not regular
-expressions. Use them like predefined constants.
-
-If the child has died and you have read all the child's output then ordinarily
-:meth:`~pexpect.spawn.expect` will raise an :class:`~pexpect.EOF` exception.
-You can read everything up to the EOF without generating an exception by using
-the EOF pattern expect. In this case everything the child has output will be
-available in the ``before`` property.
-
-The pattern given to :meth:`~pexpect.spawn.expect` may be a regular expression
-or it may also be a list of regular expressions. This allows you to match
-multiple optional responses. The :meth:`~pexpect.spawn.expect` method returns
-the index of the pattern that was matched. For example, say you wanted to login
-to a server. After entering a password you could get various responses from the
-server -- your password could be rejected; or you could be allowed in and asked
-for your terminal type; or you could be let right in and given a command prompt.
-The following code fragment gives an example of this::
-
-    child.expect('password:')
-    child.sendline(my_secret_password)
-    # We expect any of these three patterns...
-    i = child.expect (['Permission denied', 'Terminal type', '[#\$] '])
-    if i==0:
-        print('Permission denied on host. Can\'t login')
-        child.kill(0)
-    elif i==1:
-        print('Login OK... need to send terminal type.')
-        child.sendline('vt100')
-        child.expect('[#\$] ')
-    elif i==2:
-        print('Login OK.')
-        print('Shell command prompt', child.after)
-
-If nothing matches an expected pattern then :meth:`~pexpect.spawn.expect` will
-eventually raise a :class:`~pexpect.TIMEOUT` exception. The default time is 30
-seconds, but you can change this by passing a timeout argument to
-:meth:`~pexpect.spawn.expect`::
-
-    # Wait no more than 2 minutes (120 seconds) for password prompt.
-    child.expect('password:', timeout=120)
-
-Find the end of line -- CR/LF conventions
------------------------------------------
-
-Pexpect matches regular expressions a little differently than what you might be
-used to.
-
-The :regexp:`$` pattern for end of line match is useless. The :regexp:`$`
-matches the end of string, but Pexpect reads from the child one character at a
-time, so each character looks like the end of a line. Pexpect can't do a
-look-ahead into the child's output stream. In general you would have this
-situation when using regular expressions with any stream.
-
-.. note::
-
-  Pexpect does have an internal buffer, so reads are faster than one character
-  at a time, but from the user's perspective the regex patterns test happens
-  one character at a time.
-
-The best way to match the end of a line is to look for the newline: ``"\r\n"``
-(CR/LF). Yes, that does appear to be DOS-style. It may surprise some UNIX people
-to learn that terminal TTY device drivers (dumb, vt100, ANSI, xterm, etc.) all
-use the CR/LF combination to signify the end of line. Pexpect uses a Pseudo-TTY
-device to talk to the child application, so when the child app prints ``"\n"``
-you actually see ``"\r\n"``.
-
-UNIX uses just linefeeds to end lines of text, but not when it comes to TTY
-devices! TTY devices are more like the Windows world. Each line of text ends
-with a CR/LF combination. When you intercept data from a UNIX command from a
-TTY device you will find that the TTY device outputs a CR/LF combination. A
-UNIX command may only write a linefeed (``\n``), but the TTY device driver
-converts it to CR/LF. This means that your terminal will see lines end with
-CR/LF (hex ``0D 0A``). Since Pexpect emulates a terminal, to match ends of
-lines you have to expect the CR/LF combination::
-
-    child.expect('\r\n')
-
-If you just need to skip past a new line then ``expect('\n')`` by itself will
-work, but if you are expecting a specific pattern before the end of line then
-you need to explicitly look for the ``\r``. For example the following expects a
-word at the end of a line::
-
-    child.expect('\w+\r\n')
-
-But the following would both fail::
-
-    child.expect('\w+\n')
-
-And as explained before, trying to use :regexp:`$` to match the end of line
-would not work either::
-
-    child.expect ('\w+$')
-
-So if you need to explicitly look for the END OF LINE, you want to look for the
-CR/LF combination -- not just the LF and not the $ pattern.
-
-This problem is not limited to Pexpect. This problem happens any time you try
-to perform a regular expression match on a stream. Regular expressions need to
-look ahead. With a stream it is hard to look ahead because the process
-generating the stream may not be finished. There is no way to know if the
-process has paused momentarily or is finished and waiting for you. Pexpect must
-implicitly always do a NON greedy match (minimal) at the end of a input.
-
-Pexpect compiles all regular expressions with the :data:`re.DOTALL` flag.
-With the :data:`~re.DOTALL` flag, a ``"."`` will match a newline.
-
-Beware of + and * at the end of patterns
-----------------------------------------
-
-Remember that any time you try to match a pattern that needs look-ahead that
-you will always get a minimal match (non greedy). For example, the following
-will always return just one character::
-
-    child.expect ('.+')
-
-This example will match successfully, but will always return no characters::
-
-    child.expect ('.*')
-
-Generally any star * expression will match as little as possible.
-
-One thing you can do is to try to force a non-ambiguous character at the end of
-your :regexp:`\\d+` pattern. Expect that character to delimit the string. For
-example, you might try making the end of your pattern be :regexp:`\\D+` instead
-of :regexp:`\\D*`. Number digits alone would not satisfy the :regexp:`(\\d+)\\D+`
-pattern. You would need some numbers and at least one non-number at the end.
-
-
-Debugging
----------
-
-If you get the string value of a :class:`pexpect.spawn` object you will get lots
-of useful debugging information. For debugging it's very useful to use the
-following pattern::
-
-    try:
-        i = child.expect ([pattern1, pattern2, pattern3, etc])
-    except:
-        print("Exception was thrown")
-        print("debug information:")
-        print(str(child))
-
-It is also useful to log the child's input and out to a file or the screen. The
-following will turn on logging and send output to stdout (the screen)::
-
-    child = pexpect.spawn(foo)
-    child.logfile = sys.stdout
-
-Exceptions
-----------
-
-:class:`~pexpect.EOF`
-
-Note that two flavors of EOF Exception may be thrown. They are virtually
-identical except for the message string. For practical purposes you should have
-no need to distinguish between them, but they do give a little extra information
-about what type of platform you are running. The two messages are:
-
-- "End Of File (EOF) in read(). Exception style platform."
-- "End Of File (EOF) in read(). Empty string style platform."
-
-Some UNIX platforms will throw an exception when you try to read from a file
-descriptor in the EOF state. Other UNIX platforms instead quietly return an
-empty string to indicate that the EOF state has been reached.
-
-If you wish to read up to the end of the child's output without generating an
-:class:`~pexpect.EOF` exception then use the ``expect(pexpect.EOF)`` method.
-
-:class:`~pexpect.TIMEOUT`
-
-The :meth:`~pexpect.spawn.expect` and :meth:`~pexpect.spawn.read` methods will
-also timeout if the child does not generate any output for a given amount of
-time. If this happens they will raise a :class:`~pexpect.TIMEOUT` exception.
-You can have these methods ignore timeout and block indefinitely by passing
-``None`` for the timeout parameter::
-
-    child.expect(pexpect.EOF, timeout=None)
-
-.. _windows:
-
-Pexpect on Windows
-------------------
-
-.. versionadded:: 4.0
-   Windows support
-
-Pexpect can be used on Windows to wait for a pattern to be produced by a child
-process, using :class:`pexpect.popen_spawn.PopenSpawn`, or a file descriptor,
-using :class:`pexpect.fdpexpect.fdspawn`.
-
-:class:`pexpect.spawn` and :func:`pexpect.run` are *not* available on Windows,
-as they rely on Unix pseudoterminals (ptys). Cross platform code must not use
-these.
-
-``PopenSpawn`` is not a direct replacement for ``spawn``. Many programs only
-offer interactive behaviour if they detect that they are running in a terminal.
-When run by ``PopenSpawn``, they may behave differently.
-
-.. seealso::
-
-   `winpexpect <https://pypi.python.org/pypi/winpexpect>`__ and `wexpect <https://gist.github.com/anthonyeden/8488763>`__
-     Two unmaintained pexpect-like modules for Windows, which work with a
-     hidden console.

-This directory contains scripts that give examples of using Pexpect.
-
-hive.py
-    This script creates SSH connections to a list of hosts that
-    you provide. Then you are given a command line prompt. Each
-    shell command that you enter is sent to all the hosts. The
-    response from each host is collected and printed. For example,
-    you could connect to a dozen different machines and reboot
-    them all at once.
-
-script.py
-    This implements a command similar to the classic BSD "script" command.
-    This will start a subshell and log all input and output to a file.
-    This demonstrates the interact() method of Pexpect.
-
-fix_cvs_files.py
-    This is for cleaning up binary files improperly added to
-    CVS. This script scans the given path to find binary files;
-    checks with CVS to see if the sticky options are set to -kb;
-    finally if sticky options are not -kb then uses 'cvs admin'
-    to set the -kb option.
-
-ftp.py
-    This demonstrates an FTP "bookmark".
-    This connects to an ftp site; does a few ftp commands; and then gives the user
-    interactive control over the session. In this case the "bookmark" is to a
-    directory on the OpenBSD ftp server. It puts you in the i386 packages
-    directory. You can easily modify this for other sites.
-    This demonstrates the interact() method of Pexpect.
-
-monitor.py
-    This runs a sequence of system status commands on a remote host using SSH.
-    It runs a simple system checks such as uptime and free to monitor
-    the state of the remote host.
-
-passmass.py
-    This will login to a list of hosts and change the password of the
-    given user. This demonstrates scripting logins; although, you could
-    more easily do this using the pxssh subclass of Pexpect.
-    See also the "hive.py" example script for a more general example
-    of scripting a collection of servers.
-
-python.py
-    This starts the python interpreter and prints the greeting message backwards.
-    It then gives the user interactive control of Python. It's pretty useless!
-
-rippy.py
-    This is a wizard for mencoder. It greatly simplifies the process of
-    ripping a DVD to mpeg4 format (XviD, DivX). It can transcode from any
-    video file to another. It has options for resampling the audio stream;
-    removing interlace artifacts, fitting to a target file size, etc.
-    There are lots of options, but the process is simple and easy to use.
-
-ssh_tunnel.py
-    This starts an SSH tunnel to a remote machine. It monitors the connection
-    and restarts the tunnel if it goes down.
-
-uptime.py
-    This will run the uptime command and parse the output into python variables.
-    This demonstrates using a single regular expression to match the output
-    of a command and capturing different variable in match groups.
-    The regular expression takes into account a wide variety of different
-    formats for uptime output.
-
-df.py
-    This collects filesystem capacity info using the 'df' command.
-    Tuples of filesystem name and percentage are stored in a list.
-    A simple report is printed. Filesystems over 95% capacity are highlighted.

-"""CGI shell server
-
-This exposes a shell terminal on a web page.
-It uses AJAX to send keys and receive screen updates.
-The client web browser needs nothing but CSS and Javascript.
-
-    --hostname : sets the remote host name to open an ssh connection to.
-    --username : sets the user name to login with
-    --password : (optional) sets the password to login with
-    --port     : set the local port for the server to listen on
-    --watch    : show the virtual screen after each client request
-
-This project is probably not the most security conscious thing I've ever built.
-This should be considered an experimental tool -- at best.

-'''hive -- Hive Shell
-
-This lets you ssh to a group of servers and control them as if they were one.
-Each command you enter is sent to each host in parallel. The response of each
-host is collected and printed. In normal synchronous mode Hive will wait for
-each host to return the shell command line prompt. The shell prompt is used to
-sync output.
-
-Example:
-
-    $ hive.py --sameuser --samepass host1.example.com host2.example.net
-    username: myusername
-    password:
-    connecting to host1.example.com - OK
-    connecting to host2.example.net - OK
-    targeting hosts: 192.168.1.104 192.168.1.107
-    CMD (? for help) > uptime
-    =======================================================================
-    host1.example.com
-    -----------------------------------------------------------------------
-    uptime
-    23:49:55 up 74 days,  5:14,  2 users,  load average: 0.15, 0.05, 0.01
-    =======================================================================
-    host2.example.net
-    -----------------------------------------------------------------------
-    uptime
-    23:53:02 up 1 day, 13:36,  2 users,  load average: 0.50, 0.40, 0.46
-    =======================================================================
-
-Other Usage Examples:
-
-1. You will be asked for your username and password for each host.
-
-    hive.py host1 host2 host3 ... hostN
-
-2. You will be asked once for your username and password.
-   This will be used for each host.
-
-    hive.py --sameuser --samepass host1 host2 host3 ... hostN
-
-3. Give a username and password on the command-line:
-
-    hive.py user1:pass2@host1 user2:pass2@host2 ... userN:passN@hostN
-
-You can use an extended host notation to specify username, password, and host
-instead of entering auth information interactively. Where you would enter a
-host name use this format:
-
-    username:password@host
-
-This assumes that ':' is not part of the password. If your password contains a
-':' then you can use '\\:' to indicate a ':' and '\\\\' to indicate a single
-'\\'. Remember that this information will appear in the process listing. Anyone
-on your machine can see this auth information. This is not secure.
-
-This is a crude script that begs to be multithreaded. But it serves its
-purpose.

-CMD_HELP='''Hive commands are preceded by a colon : (just think of vi).
-
-:target name1 name2 name3 ...
-
-    set list of hosts to target commands
-
-:target all
-
-    reset list of hosts to target all hosts in the hive.
-
-:to name command
-
-    send a command line to the named host. This is similar to :target, but
-    sends only one command and does not change the list of targets for future
-    commands.
-
-:sync
-
-    set mode to wait for shell prompts after commands are run. This is the
-    default. When Hive first logs into a host it sets a special shell prompt
-    pattern that it can later look for to synchronize output of the hosts. If
-    you 'su' to another user then it can upset the synchronization. If you need
-    to run something like 'su' then use the following pattern:
-
-    CMD (? for help) > :async
-    CMD (? for help) > sudo su - root
-    CMD (? for help) > :prompt
-    CMD (? for help) > :sync
-
-:async
-
-    set mode to not expect command line prompts (see :sync). Afterwards
-    commands are send to target hosts, but their responses are not read back
-    until :sync is run. This is useful to run before commands that will not
-    return with the special shell prompt pattern that Hive uses to synchronize.
-
-:refresh
-
-    refresh the display. This shows the last few lines of output from all hosts.
-    This is similar to resync, but does not expect the promt. This is useful
-    for seeing what hosts are doing during long running commands.
-
-:resync
-
-    This is similar to :sync, but it does not change the mode. It looks for the
-    prompt and thus consumes all input from all targeted hosts.
-
-:prompt
-
-    force each host to reset command line prompt to the special pattern used to
-    synchronize all the hosts. This is useful if you 'su' to a different user
-    where Hive would not know the prompt to match.
-
-:send my text
-
-    This will send the 'my text' wihtout a line feed to the targeted hosts.
-    This output of the hosts is not automatically synchronized.
-
-:control X
-
-    This will send the given control character to the targeted hosts.
-    For example, ":control c" will send ASCII 3.
-
-:exit
-
-    This will exit the hive shell.

-''' This runs a sequence of commands on a remote host using SSH. It runs a
-simple system checks such as uptime and free to monitor the state of the remote
-host.
-
-./monitor.py [-s server_hostname] [-u username] [-p password]
-    -s : hostname of the remote server to login to.
-    -u : username to user for login.
-    -p : Password to user for login.
-
-Example:
-    This will print information about the given host:
-        ./monitor.py -s www.example.com -u mylogin -p mypassword
-
-It works like this:
-    Login via SSH (This is the hardest part).
-    Run and parse 'uptime'.
-    Run 'iostat'.
-    Run 'vmstat'.
-    Run 'netstat'
-    Run 'free'.
-    Exit the remote host.

-''' This runs netstat on a local or remote server. It calculates some simple
-statistical information on the number of external inet connections. It groups
-by IP address. This can be used to detect if one IP address is taking up an
-excessive number of connections. It can also send an email alert if a given IP
-address exceeds a threshold between runs of the script. This script can be used
-as a drop-in Munin plugin or it can be used stand-alone from cron. I used this
-on a busy web server that would sometimes get hit with denial of service
-attacks. This made it easy to see if a script was opening many multiple
-connections. A typical browser would open fewer than 10 connections at once.
-A script might open over 100 simultaneous connections.
-
-./topip.py [-s server_hostname] [-u username] [-p password]
-        {-a from_addr,to_addr} {-n N} {-v} {--ipv6}
-
-    -s : hostname of the remote server to login to.
-    -u : username to user for login.
-    -p : password to user for login.
-    -n : print stddev for the the number of the top 'N' ipaddresses.
-    -v : verbose - print stats and list of top ipaddresses.
-    -a : send alert if stddev goes over 20.
-    -l : to log message to /var/log/topip.log
-    --ipv6 : this parses netstat output that includes ipv6 format.
-        Note that this actually only works with ipv4 addresses, but for
-        versions of netstat that print in ipv6 format.
-    --stdev=N : Where N is an integer. This sets the trigger point
-        for alerts and logs. Default is to trigger if the
-        max value is over 5 standard deviations.
-
-Example:
-
-    This will print stats for the top IP addresses connected to the given host:
-
-        ./topip.py -s www.example.com -u mylogin -p mypassword -n 10 -v
-
-    This will send an alert email if the maxip goes over the stddev trigger
-    value and the the current top ip is the same as the last top ip
-    (/tmp/topip.last):
-
-        ./topip.py -s www.example.com -u mylogin -p mypassword \\
-                -n 10 -v -a alert@example.com,user@example.com
-
-    This will print the connection stats for the localhost in Munin format:
-
-        ./topip.py

-*                  Welcome to the SOCKET UNIT TEST code!                     *
-------------------------------------------------------------------------------
-*                                                                            *
-* This unit test code is our best effort at testing the ability of the       *
-* pexpect library to handle sockets. We need some text to test buffer size   *
-* handling.                                                                  *
-*                                                                            *
-* A page is 1024 bytes or 1K. 80 x 24 = 1920. So a standard terminal window  *
-* contains more than one page. We actually want more than a page for our     *
-* tests.                                                                     *
-*                                                                            *
-* This is the twelfth line, and we need 24. So we need a few more paragraphs.*
-* We can keep them short and just put lines between them.                    *
-*                                                                            *
-* The 80 x 24 terminal size comes from the ancient past when computers were  *
-* only able to display text in cuneiform writing.                            *
-*                                                                            *
-* The cunieform writing system used the edge of a reed to make marks on clay *
-* tablets.                                                                   *
-*                                                                            *
-* It was the forerunner of the style of handwriting used by doctors to write *
-* prescriptions. Thus the name: pre (before) script (writing) ion (charged   *
-* particle).                                                                 *

-This file is a VT100-series Torture Test.  It demonstrates all the visual
-attributes of the VT100 terminal.
-
-The top line is double-width/single-height with inverse-video line-drawing
-characters.  The 2nd and 3rd lines are double-width/double-height in bold
-inverse video.  They also show the limited scrolling region.
-
-The remaining lines will show NORMAL, BOLD, BLINK, INVERSE, and all 16
-combinations of those 4 attributes.  They show that there is a difference
-between an underscore character and the underline attribute, and that
-lower-case decenders go below the underline.
-
-A window pane is drawn in the lower right to show how the line-drawing set
-can be used.  At the lower left is the character set double-wide/double-high
-to show the dot-matrix used.  Upper-case characters are 8 by 7 in a 10 by 10
-character cell, with 1 blank row on top and 2 on the bottom.  The underline
-attribute uses the first bottom blank row, lower-case decenders use both.

-This tool uses pexpect to test expected Canonical mode length.
-
-All systems use the value of MAX_CANON which can be found using
-fpathconf(3) value PC_MAX_CANON -- with the exception of Linux
-and FreeBSD.
-
-Linux, though defining a value of 255, actually honors the value
-of 4096 from linux kernel include file tty.h definition
-N_TTY_BUF_SIZE.
-
-Linux also does not honor IMAXBEL. termios(3) states, "Linux does not
-implement this bit, and acts as if it is always set." Although these
-tests ensure it is enabled, this is a non-op for Linux.
-
-FreeBSD supports neither, and instead uses a fraction (1/5) of the tty
-speed which is always 9600.  Therefor, the maximum limited input line
-length is 9600 / 5 = 1920.
-
-These tests only ensure the correctness of the behavior described by
-the sendline() docstring -- the values listed there, and above should
-be equal to the output of the given OS described, but no promises!

-What is a pty?
---------------
-
-A pty is a kernel-level object which processes can write data to and read data
-from, a bit like a pipe.
-
-Unlike a pipe, data moves through a single pty in both directions. When you use
-a program in a shell pipeline, or with :class:`subprocess.Popen` in Python, up
-to three pipes are created for the process's standard streams (stdin, stdout
-and stderr). When you run a program using ptyprocess, all three of its standard
-streams are connected to a single pty:
-
-.. image:: images/pty_vs_popen.png
-
-A pty also does more than a pipe. It keeps track of the window size (rows and
-columns of characters) and notifies child processes (with a SIGWINCH signal)
-when it changes. In *cooked mode*, it does some processing of data sent from the
-parent process, so for instance the byte ``03`` (entered as Ctrl-C) will cause
-SIGINT to be sent to the child process.
-
-Many command line programs behave differently if they detect that stdin or stdout
-is connected to a terminal instead of a pipe (using 
-`isatty() <http://linux.die.net/man/3/isatty>`_), because this normally means
-that they're being used interactively by a human user.
-They may format output differently (e.g. ``ls`` lists files in columns)
-or prompt the user to confirm actions.
-When you run these programs in ptyprocess, they will exhibit their 'interactive'
-behaviour, instead of the 'pipe' behaviour you'll see using ``Popen()``.
