group names (unix) are strings like bin, prog, etc.
If you want to check the validity of a group name: example, assume
Code:
myscript.sh grpnam

is what the user types, then this will check it
Code:
grep -q "$1" /etc/group
if [[ $? -eq 0 ] ; then
   "$1 is a valid group"
else
   "$1 is not a valid group"
    exit 1
fi
# ........ more code down here ..............
