SYNOPSIS

       wtmpdb COMMAND [option...]

DESCRIPTION

       entries.

       This command is Y2038 safe and uses sqlite3 to store the information.

COMMANDS

       The following commands are understood:

       last [option...] [username...] [tty...]
           wtmpdb last goes through the /var/lib/wtmpdb/wtmp.db database (or the database
           designated by the -f option) and displays a list of of all users logged in and logged
           out. The output can be restricted to different patterns via various options. If one or
           more usernames and/or ttys are given wtmpdb last will only show the entries matching
           those arguments.

           The login and logout times of the special user reboot are the boot and shutdown times
           of the system.

               Translate IP addresses into a hostname.

               Use FILE as wtmpdb database.

           -F, --fulltimes
               Display full times and dates.

               Display timestamps in the specified FORMAT. The format can be notime, short, full,
               or iso.  notime will not display times at all, short is the default option, full
               will display the full times and dates, and iso will display times in ISO-8601
