[SOLVED] How to print linux group names on multiple line instead of single line output

Issue

I have tried getent, group command, id -Gn $user and some sed combination but I don't think I am able to achieve hence reaching out to fellow programmers.
I want to be able to print this : groups abc123
Output abc123 : devops build test design

Expected Output
groups:
- devops
- build
- test
- design

Solution

From what I see, you are trying to convert the groups of your user to an yaml array, try to use:

echo "groups:" ; for i in $(id -Gn myuser);do echo "  - $i" ;done

groups:
  - users
  - lp
  - vboxusers
  - kvm

You can use too:

echo "groups: [ $(groups myuser | sed -e 's/.\+\s\+:\s\+\(.\+\)/\1/g' -e 's/\(\s\+\)/, /g') ]"

groups: [ myuser, lp, vboxusers, kvm ]
