Get fullname by username using SSSD

  • 772

The OS uses SSSD to authenticate users via LDAP. It has no X server running. I can run id <username> to get the uid of the user. And the users can login to the system and their full name is displayed.

Is there a way to get the full name or display name of a specified user via a shell command?

  1. getent passwd <username> should do the trick.

  3. sssd 1.13+ provides a D-BUS query interface.

  4. Depending on your UNIX version you can use

    echo $LOGNAME

    or

    echo $USER

    If both $LOGNAME and $USER are present they should match.
