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
   ...              .......        ............................................

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
