how to display users under a group in a line for each user in Linux bash

Currently when I run a grep command on a visitors group that I had created

grep visitors:x:1011: /etc/group

This is a sample result of the above command, as the actual result is too long.

visitors:x:1011:ellipsiscoterie,magnetcommonest,wizardmeans,beakskeletal,lemonwellmade,ralphpaperclips etc..

How do I display the above result as shown below (without visitors:x:1101 and separating the commas), as I have difficulty doing so.

ellipsiscoterie
magnetcommonest
wizardmeans
beakskeletal
lemonwellmade
ralphpaperclips
Solution

  • I suggest using sed instead of grep

    sed -n -e 's/^visitors\:x\:1011\://p' /etc/group | tr ',' '\n'

    UPD: detailed explain of sed part is here. tr examples you can find here
