Works on command line but not in script
Hey guys. Hopefully this is an easy one but having reference similar problems on the web I still can't fix it.

I am doing a recursive find and replace from a script. Of course I could just run the damn thing from the command line but it's bugging me now and want to get it working.
Code:
grep -rl $1 * | xargs sed -i 's/$1/$2/g'

The above line is the basic command line I am using. When I replace the variables with real text on the command line it works just fine.

When I run that line inside my script with two inputs and echo out the line the line is exactly as it should be, but when executed from within the script it does zilch, nada, nothing.

At the top of my script I included:
Code:
#!/bin/bash
SHELL=/bin/bash
MAIL=/var/mail/root
PATH=/opt/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

These are exactly the same if you type env

Am I missing something?

Many thanks

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
