<div><a href="http://david-halliday.co.uk/?Linux:Make_/home/"></a> (I wanted them to have a /home on a linux box so they had FTP, SSH and (as a result of a public_html directory) HTTP web hosting easily configured for educational purposes. While that wbinfo command is for ad users there might be something else but I can't find it yet.</div>

<br>
I always assumed managing users would be a lot simpler in linux, but im<br>
struggling to find an easy way to add 500+ users into groups. Got a<br>
couple of groups that I need all users to be a part of.<br>
<br>
#!/bin/sh<br>
<br>
for USER in userA userB userC userD userE; do<br>
usermod -G USERS $USER<br>
done<br>
<br>
script above should do the trick, but then I'd need to get a list of all<br>
my usernames in the correct format, ie userA userB userC, so i'd have to<br>
use a combination of awk/sed/whatever on /etc/passwd. Is there an easier<br>
way?<br>
<br>
cheers<br>
