From 89c8230dec063d894aec1a7b5c58f1dcadced738 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Wed, 2 Apr 2014 10:20:05 +0200 Subject: new commands: uuid and guid - generate random unique identifier Those commands basis on implementation of random UUID generator version 4 which is described in RFC4122. The same algorithm is used for generation both ids but string representation is different as below. char: 0 9 14 19 24 36 xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx UUID: be be be be be GUID: le le le be be Commands usage: - uuid [] - guid [] The result is saved in environment as a "varname" variable if argument is given, if not then it is printed.
