Registered User

'useradd' takes care of all that. It will also add the default directory and files in the new home directory and add the appropriate entries into /etc/passwd and /etc/shadow. No need for a counter. See previous comments for more information.

If you have to use a counter, these constructs will work also.

Code:

i=$userid
i=$(($i + 1))
#OR
let i=$userid
let i=++i;

But, then you'll have to find the highest UID and GID values in /etc/passwd for regular users. That will involve reading /etc/login.defs to get UID_MIN, UID_MAX, GID_MIN, GID_MAX and reading all of /etc/passwd for maximum valid UID and GID values. It's just not worth it. 'useradd' is much easier. To create password run 'passwd $user' after 'useradd'. So that's...

Code:

# if $dept doesn't exist
#   create new group with 'groupadd'
#   gid = dept's GID
#   create dir for dept
#   'chgrp' for dir of dept
# else
#   gid = dept's GID
# fi
useradd -m -d "/home/$dept/$user" -g $gid -K UMASK=026
passwd $user
