What OS are you using?
Run the command and post results: uname -a
What shell are you using? Unix is not a shell.
Run the command and post results: echo $SHELL
What does the data look like? - Your answer isn't much to go on - unless you post an example of the data, you may be on your own for this. You won't be able to write a script if you don't know what the data looks like to grab the information you need. We can't help since we don't have any clue on what the data looks like.
What programming language have you selected?
sh, ksh, csh, bash, tcsh, .... are examples of shells. Each can be used to write a shell script.
What specifically can you not figure out? 6) how to analyse the file so i can give a page count per account number.
We can't assist without knowing the layout of the file - if you can't post the format or part of the file (as it may be something you can't share with outsiders), then you need to look at it and figure it out.
How do you do this processes today (if at all)? Normally if you can look at how the process is done manually, you can code something to do it automatically.

CHSH(1) User Commands CHSH(1)
NAME
chsh - change login shell
SYNOPSIS
chsh [options] [LOGIN]
DESCRIPTION
The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
the login shell for her own account; the superuser may change the login shell for any account.
OPTIONS
The options which apply to the chsh command are:
-h, --help
Display help message and exit.
-R, --root CHROOT_DIR
Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.
-s, --shell SHELL
The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.
If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.
NOTE
The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
back to its original value.
FILES
/etc/passwd
User account information.
/etc/shells
List of valid login shells.
/etc/login.defs
Shadow password suite configuration.
SEE ALSO
chfn(1), login.defs(5), passwd(5).
