      whoami

      whoami tells you your current username.

      Examples:

      $ whoami
abicool

      groups

      groups states the groups the current user is a member of

      Examples:

      $ groups
wheel slocate www

      id

      id gives you the same information as the whoami and groups commands, but also includes the user id (uid) and group id (gid) integers associated with the login.

      Examples:

      $ id
uid=3426(alice) gid=10(wheel)
groups=10(wheel),21(slocate),401(www)

      tty

      tty tells you the terminal device that is assigned to your interactive login. The tty represents your console device, network connection ("ssh", ...), or terminal emulator process ("xterm", "konsole", ...).

      Examples:

      $ tty
/dev/pts/14
