I have several shell scripts to manage user accounts on a server. I've been using a file with the usernames of peoples accounts that any script needs to process. I had a thought that I can and should be setting up groups and adding user accounts to those groups so I don't have to maintain a set of files with the user accounts.
So essentially, I am looking for a (simple) shell command to run from a bash script that will allow me to list user accounts that belong to a particular group. Any help is appreciated.
