Hi,
Below commands will satisfy your requirement.
List the users belong to the group
$ lid -g groupname| cut -f1 -d'('
Or
$ egrep -i "^groupname" /etc/group|awk -F : '{print $4}'
To print the primary group membership for a user:
$ id -g -n username
To print the secondary group membership for a user:
$ id -G -n username
Regards,
M.Naresh Kumar

This would be a classic use case for awk. Split fields by colons and
then display all the fourth fields where the first field is the group
name:
awk 'BEGIN { FS = ":" } $1 ~ /powerdev/ { print $NF}' /etc/group
I can help further if needed.
Thanks.

Spamassassin tries to figure out heuristically if a message is
spam. It does this by applying many rules to the message, and
assigning each rule a score (positive OR negative) ... If the
score goes above a predefined number, it's flagged as spam and
you can do the rest. [Visit: http://www.spamassassin.org].
