This is a script i wrote for my mates shell server, it does the following:

-Checks for certain binarys that are installed
-Creates a random password
-Interactivly lets you setup the users email | home | shell | name | nick
-Emails the user there username, password and domain (depending)
-Adds them to a list held in /root/userlist

The program was based off the adduser script found at osix.net, i modified it and my friend bob added the binary checking script to it.

This is a good bash script to learn some things off and to also modify for personal use. This is not an optomised script though things can be done better.

Enjoy

This script is great, but it doesn't set the password correctly. If you are going to use the -p flag on useradd you must first encrypt the password or else the user will not be able to log in.

add this:
PASSCRYPTED=$(perl -e 'print crypt($ARGV[0], "password")' $PASS)

and then change the useradd line to this:
useradd -d $HOME -p $PASSCRYPTED -g $GROUP -s $SHELL $USERNAME

Also you may notice some problems with the chown command on line 376:
chown $USER:$GROUP $HOME

should read:
