What is the id command?

The id command in Linux is a utility that displays user and group information for the current user or a specified user. It provides the following details:

• User ID (UID): A unique identifier for the user.
• Group ID (GID): The primary group identifier for the user.
• Groups: A list of all groups the user belongs to, including their IDs.

Basic Usage:

To use the id command, simply type:

id

Example Output:

uid=1001(labby) gid=1001(labby) groups=1001(labby),27(sudo)

This output indicates:

• The username is labby.
• The user ID is 1001.
• The primary group is also labby with GID 1001.
• The user belongs to the sudo group as well.
