As for setting their passwords, the chpasswd command may be what you need. Chpasswd likes ":" between username and password, while you have spaces in your file. So edit the file and remember to set IFS=: at the beginning of your script. I usually don't trust enough my own scripting skills. So I'm reluctant to make a script that may radically change the state of my system's user base. You may feel more comfortable making a script which simply builds up and outputs the proper commands, gather this output into a file, give it a good look and only then execute these commands. -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina
