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

service

SERVICE(8)						    BSD System Manager's Manual 						SERVICE(8)

NAME

     service -- control (start/stop/etc.) or list system services

SYNOPSIS

     service -e
     service -R
     service [-v] -l | -r
     service [-v] <rc.d script> start|stop|etc.

DESCRIPTION

     The service command is an easy interface to the rc.d system.  Its primary purpose is to start and stop services provided by the rc.d scripts.
     When used for this purpose it will set the same restricted environment that is in use at boot time (see below).  It can also be used to list
     the scripts using various criteria.

     The options are as follows:

     -e  List services that are enabled.  The list of scripts to check is compiled using rcorder(8) the same way that it is done in rc(8), then
	 that list of scripts is checked for an "rcvar" assignment.  If present the script is checked to see if it is enabled.

     -R  Restart all enabled local services.

     -l  List all files in /etc/rc.d and the local startup directories.  As described in rc.conf(5) this is usually /usr/local/etc/rc.d.  All
	 files will be listed whether they are an actual rc.d script or not.

     -r  Generate the rcorder(8) as in -e above, but list all of the files, not just what is enabled.

     -v  Be slightly more verbose

ENVIRONMENT

     When used to run rc.d scripts the service command sets HOME to / and PATH to /sbin:/bin:/usr/sbin:/usr/bin which is how they are set in
     /etc/rc at boot time.

EXIT STATUS

     The service utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     The following are examples of typical usage of the service command:

	   service named status
	   service -rv

     The following programmable completion entry can be use in bash(1) for the names of the rc.d scripts:
	   _service () {
		local cur
		cur=${COMP_WORDS[COMP_CWORD]}
		COMPREPLY=( $( compgen -W '$( service -l )' -- $cur ) )
		return 0
	   }
	   complete -F _service service

SEE ALSO

     bash(1) (ports/shells/bash), rc.conf(5), rc(8), rcorder(8)

HISTORY

     The service utility first appeared in FreeBSD 7.3.
