How to list all users in a group?

You can list all users in a specific group in Linux using the following methods:

1. Using the getent Command

You can use the getent command to retrieve group information, which includes the list of users in that group:

getent group groupname

Example

To list all users in a group called developers:

getent group developers

The output will show the group name, password placeholder, GID, and a comma-separated list of users in that group.

2. Using the /etc/group File

You can also check the /etc/group file directly:

cat /etc/group | grep groupname

Example

To find users in the developers group:

cat /etc/group | grep developers

Summary

Both methods will provide you with a list of users belonging to a specified group. The getent command is generally preferred for its simplicity and reliability.
