List all users and their corresponding groups
In Linux to list all users and groups for which they are member:
cat /etc/passwd | awk -F ':' '{print $1 }' | xargs -n1 groups
In other way round to see which users belong to a particular group we can use above output and grep for groupname. Such as
cat /etc/passwd | awk -F ':' '{print $1 }' | xargs -n1 groups | grep <group1>
Getent information of a group
Please note that genent group might not be sufficient as users primary group information would be in /etc/passwd and wont be shown in this output. For example
getent group root
on CentOS might show group root not having any members. However doing
groups root
will show user root belonging to group root
