## Prep a temporary filename, to hold the list of filenames.
##      We put the outlist file in /tmp, in case the user
##      does not have write-permission in the current directory,
##      and because the output of 'last' does not, usually,
##      have a direct relation to the current directory.

$SCRIPT_DIRNAME


  The list was created with the 'last -F' command.

If you want to change the output of this script,
you can simply edit the script.

------------------------------------------------------------------------------
FOR MORE INFO ON OUTPUT OF 'last':

You can type 'man last' in a terminal to see details on
how the program can be used.

('man' stands for Manual.  It gives you the user manual
 for the command/utility.)

You can type 'man man' at a shell prompt to see a description
of the 'man' command.

Or use the 'show_manhelp_4topic' Nautilus script in the
'LinuxHELPS' group of Nautilus scripts. Enter 'last' at
the prompt for a command/topic.

---

The 'last' command lists the contents of log files
/var/log/wtmp and /var/log/btmp --- which hold information
on the recent logins to this host.
