bash script for showing last users

Hi! I'm new in scripting and I need some help with one simple script. I have to write a program that shows in a predetermined period (using "last" command), to draw up a list of users who have used the machine during this period. Each user to indicate how many sessions it has been during this period. Output must be sorted alphabetically by usernames (increasing alphabetically).

The code should be something like???:
Code:
cat lastfile | cut -c1-8 | egrep -v '(^reboot)|(^$)|(^wtmp a)|(^ftp)' | sort | uniq -c | sort -rn

But how to I predetermine the period and sort alphabetically(increasing)?

Regards,
Vassu

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. CMU
