Making a script for editing
Hello all. I am trying to make a script to edit any file by replacing a string with a string. The script should be able to be applied to any given file. for instance it should be able to replace "foo" with "bar" in the file myFile.txt. I know i need to make a back up file for this to work. I just dont know how to make the sed command for a file that has to be inputted. so far i have

#!/bin/sh
sed s/$1/$2/g ---this is where the input file name should be right??---

My script is called subst1. So i should be able to give the command

./subst1 $1 $2 -file name??-

any words of wisdon would be greatly appreciated.

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.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

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.
