A user is an entity, in a Linux operating system, that can manipulate files and perform several other operations. Each user is assigned an ID that is unique for each user in the operating system. In this post, we will learn about users and commands which are used to get information about the users.

How do you find out what groups a user is in?

Method 2 – id command The another way to identify the groups a user is in is by using “id” command. The id command is used to print user and group information for the specified USER. If the USER is not specified, it will print the information for the current user.
