Shell Programming and Scripting
Sorting group information for accounts

So far this works for me - still testing. I'm not familiar w/ using arrays or built-in awk variables but I've been googling and will eventually practise to become more knowledgeable. I've made a few tweaks:
The secondary groups actually start in field 11, so after a bit of tinkering I changed "i" to 11 instead of 4. For some reason the output is always preceded by a "it doesn't exist!" error but the user is also properly included in the respective groups output by the script.
The groups and respective GID's have slight conflicts per server (maybe 5% of the GID's conflict across all servers) so what i typically do is pull them all into 1 big file then sort and uniq them. So, instead of "getent" I replaced that with "cat <group_file>" and it seems to work. I just need to make sure the tool that accepts the group upload file will notify of any conflicts and not wipe out anything which I will do.
I still have a lot to learn about this script but does that sound right - replacing i with 11 instead of 4? Everything appears to check out so far.
Edit: Darn - I also have to sort GID upload files by server so I upload them to the proper one
It just gets better and better!

lnewusers(1) General Commands Manual lnewusers(1) NAME
lnewusers - Create new user accounts SYNOPSIS
lnewusers [OPTION]... DESCRIPTION
Creates new user accounts using data read from standard input. The input data consists of lines, each line has 7 colon-separated fields: User name Plaintext password User ID lnewusers refuses to create users with user ID 0 (the root user ID). Group If this field is a valid group ID, it is interpreted as a group ID, otherwise as a group name. If the field is empty, a group name equal to user name is used. If the specified group does not exist, it is automatically created. If the group is specified with a group ID, the created group has group name equal to the user name. GECOS The GECOS field is traditionally used to store user's real name and other information. Home directory If this field is empty, a default specified by libuser configuration, or /home/username if libuser configuration does not specify a default, is used. Login shell If this field is empty, a default specified by libuser configuration is used. Errors in user specifications are reported and processing continues on the next line. OPTIONS
-f, --file=file Read account data from file instead of standard input. -i, --interactive Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration. -M, --nocreatehome Don't create home directories. -n, --nocreatemail Don't create mail spool files. EXIT STATUS
The exit status is 0 on success, nonzero on fatal error. Errors in user specifications are not reflected in the exit status. libuser Jul 13 2008 lnewusers(1)
