TAGS: linux permissions terminal commandline

In Linux (and most OSes), you're sorted into user groups, and users.

For example:

The Gamer group doesn't have permissions to delete the hard drive.

These commands will help you figure out what group you're in, and if you belong to the group that can modify files.

$ groups
$ groups nginx
$ grep 'web' in /etc/group
