What are best practices for using id command?

The id command in Linux is used to display user and group information for the current user or a specified user. Here are some best practices for using the id command:

  • Use id without options to display your own user and group information.
  • Specify a username as an argument to view information about that user.
  • Combine id with other commands using pipes to filter or format the output.
  • Check the effective user and group IDs when debugging permission-related issues.

Example:
