Hi all, may you write me how to get (for example) the list of all the teachers?
I mean by bash, not by LWAT.
I need that for a script.


getent group teachers |cut -d: -f4 |tr ',' '\n'

[getent group teachers] will also list name of group, gid, users etc, but you probably just want the usernames. So piping the output to [cut -d: -f4] will show only the 4th field, the 4th field being the user names. The users will then be listed on one line, separated by commas. Then when you add [tr ',' '\n'] it translates all commas to new lines, so the result will be a list with all users in teachers group, each username on a new line
