Hi,

you can pass file name as a argument to Your shell script like this

$ script.sh filename

in shell script arguments are stored into special variables i.e first argument is stored into $1,second in $2 .....if you want to get all arguments in one go use $*.

so inside the script use :

$ filename=$1 #to get the file name.

Then use for loop to get the contents of file like this..

for i in `cat $filename`
do
firstline=$i
your logic..........

done

Note : if the file location is differ then script location the use relative path name as :
$ script.sh /home/rajiv/filename

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
