rawtmp - display wtmp entries in raw form.

       Could use some filtering options.

Rawtmp  is  a  utility  to dump the raw data in a wtmp or utmp file to the screen for viewing.  It may be
       useful to anyone who wishes to divine the nature of the data stored in the wtmp or utmp  files.   It  may
       also  be useful to extract special wtmp entries that are not documented anywhere (like those netdate puts
       in the wtmp file).

       If on a logout, when the username is encoded in the ut_user field by replacing the first character of the
       username with a null, rawtmp will print the contents of the user field with a leading dot '.'  to  denote
       the  null  character.  Only  agetty  and  tacacs control software are currently known to use this logging
       method.

/var/log/wtmp        login database.

       rawtmp - display wtmp entries in raw form.

Rawtmp understands the following command line switches:

       --help Outputs a verbose usage listing.

       --version
              Displays the version of rawtmp.

       -wwtmp
              Select a different input file instead of the default (/var/log/wtmp).

       -X[3]  Read a wtmp file maintained by versions 3.3 or 3.4 Tacacs terminal server access control software.

       -X4    Read a wtmp file maintained by version 4.0 of Tacacs terminal server access control software.

       -d     Output the time in MMM DD HH:MM:SS format instead of raw time for a more human readable form  (and
              to actually know what day you're looking at!).

       -a     Print  the  contents  of  the ut_addr field (in quad-dotted notation) instead of using the ut_host
              field.  Note: ut_addr is almost never used and more than likely contains garbage information.

       -bhours[:minutes[:seconds]]
              Consider only those utmp entries that fall within the  last  few  hours/minutes/seconds  from  the
              current time, disregarding the rest.

       -sstart
              Selects the starting date of the report, in mm/dd/yy format.

       -eend Selects the ending date of the report, in mm/dd/yy format.
