Tom,
field 4 of the /etc/passwd file gives the group id of the user.

Hi,

if you want gid as number try this:
id | awk '{print $2}' | sed 's/gid=$[0-9]*$(.*/\1/'

ex: of case

GID=`id | awk '{print $2}' | sed 's/gid=$[0-9]*$(.*/\1/'`

case "$GID" in
'20')
echo "User group"
;;
'3')
echo "This is sys group"
;;
*)
esac

# id -g # Prints effective GUID
# id -gn # Print GID as name

Examle:

# id -g
3
# id -gn
sys

Script: (We expect GID as number)

GID=`id -g`

case "$GID" in
'3') do somthing;;
'1025') do somthing;;
*) do default;;

esac
