It means that user inserts some date [example input: Oct 26 11:00 - Oct 27 14.00] and script output shows all users, who have been logged in during this time, alphabetically. And shows how many sessions they have had in this period. Somehow it can be predetermined to show according to "date" field. Right now without script it shows like this:

Code:

frogger rubiin/wazzar> cat lastfile | cut -c1-8 | egrep -v '(^reboot)|(^$)|(^wtmp a)|(^ftp)' | sort | uniq -c | sort -k 1 | last -10

Script should show something like this:

Code:

Example:\\>users.sh  Oct 26 11:00 - Oct 27 14.00
 SESSIONS      USER              LAST LOGIN
   12              userA      Tue Oct 27 13:45 - 13:50  (00:04)
    3               userB      Tue Oct 27 13:31   still logged in
    5               userC      Tue Oct 27 13:31   still logged in
   ...              .......        ............................................

pts_quit

PTS_QUIT(1)						       AFS Command Reference						       PTS_QUIT(1)

NAME

       pts_quit - Exit from pts interactive mode

SYNOPSIS

       pts quit [-cell] <cell name> [-noauth] [-localauth]
	   [-force]

       pts q [-c] <cell name> [-n] [-l] [-f]

DESCRIPTION

       The pts quit command exits from pts interactive mode.  The command can be run from the command line or interactively, but on the command
       line it does nothing and is therefore of questionable utility.

CAUTIONS

       Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts quit command was only available on Unix or Linux and when OpenAFS was compiled with the
       supergroups option (disabled by default).  As of OpenAFS 1.4.5 and 1.5.23, it is always available.

OPTIONS

       Although they have no effect, pts quit takes the following standard pts options:

       -cell <cell name>
	   Names the cell in which to run the command. For more details, see pts(1).

       -force
	   Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the
	   first error.

       -help
	   Prints the online help for this command. All other valid options are ignored.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or
	   -noauth options. For more details, see pts(1).

       -noauth
	   Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1).

OUTPUT

       This command produces no output.

EXAMPLES

       Here is an example of a pts interactive session:

	  % pts interactive
	  pts> quit
	  %
