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.

Quotation

groups <username>

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

Quotation

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:

Quotation

geek@ubuntuServ:$ groups root
root : root fuse
