@jabi in addition to Terrance link this could be helpful too grep -iE "^adm" /etc/group | cut -d":" -f4- — George Udosen, Oct 25 '17 at 21:42

Several options are available:

getent group <group_name> | cut -d":" -f4-

or

grep -iE "^adm" /etc/group | cut -d":" -f4-

Note you have to add the group name where I have "^adm, this will present members of that group.

See: man getent

If you know the (full) group name, then you can give it as a key to getent directly (avoiding the call to grep) e.g. getent group workers – steeldriver Oct 26 '17 at 02:20
