Top Forums Shell Programming and Scripting Generate unique user id with each addition of data Post 302577443 by balajesuri on Tuesday 29th of November 2011 05:22:06 AM

* How long can this unique user id be?
* In one of my scripts, I had used the following to generate a unique string. See if this helps:
Code:
USER_ID="user`date +%Y%m%d%H%M%S`"

Of course, if you were to use the variable USER_ID more than once within a second, then this would fail.
