The id command in Linux is used to display 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 that the user belongs to.
For example, running id without any arguments will show information for the current user, while id username will show information for the specified user.
