From 4955a31cecb698def9eb4b395fc297e56f76d492 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 5 Apr 2014 18:24:43 +0200 Subject: support/mkusers: fix warnings when adding a new user When adding a new user (or a new group), we would get warnings, like: [...]/support/scripts/mkusers: line 145: [: too many arguments This is because we're checking if a UID (or a GID) is already defined, and/or is different from the requested one, both checks in the same test. Of course, if a UID (or a GID) is not defined, it does not have a value, so we can not compare it to an integer. Fix that by splitting the test in two, so the second is only executed if the first is sucessful. Reported-by: Thomas Petazzoni Signed-off-by: "Yann E.
