See Which Groups Your Linux User Belongs To

When you are using a linux system, it’s useful to find out what groups you belong to, so you can understand whether you have access to files and directories. This is one of the simplest commands possible. I’m using Ubuntu linux, but this command should work on most varieties of linux.

groups <username>

If you don’t enter a username, it defaults to your own username. For instance:

geek@ubuntuServ:$ groups
geek adm dialout cdrom floppy audio dip video plugdev lpadmin scanner admin fuse

You can also check the groups for any other user, including root:

geek@ubuntuServ:$ groups root
root : root fuse

I used this command recently to make sure that my user account was part of the “fuse” group, when I was getting sshfs set up. Very useful.

    Thank you so much dude that really helped. I was trying to implement user rights based on groups because i several people that wanted to run one single service with maximum rights and all of them belong to the QA group.

    Now the issue is resolved and yes your command groups helped me to identify the group of various users.
