Simple Shell Script! Almost Done!
Hello, I am creating a shell script and I am almost done. I have certain things I want done in the shell but don't know how to finish it properly.



Here is what I am aiming to do. I am aiming to have a shell that takes at least 3 parameters. The first two are the two words to replace (the first being the word replaced and the second being the word to replace it with) and then the third (and beyond) parameter, are all the files to make the changes to.

Here is what I have so far but its not working correctly and giving me incorrect output when using special characters such as changing 'Unix' to 'U N I X'



Code:
#!/bin/sh

replace=$1
shift
with=$1
shift
for file in $*
do
   echo $file

newreplace=`echo "$replace" | sed -e "s/$replace/&/g"`

echo $newreplace

sed "s/$newreplace/$with/g" "$file" > "$file.updated"
mv "$file.updated" "$file"
done

grub-install.unsupported

GRUB-INSTALL(8) 							FSF							   GRUB-INSTALL(8)

NAME

       grub-install - install GRUB on your drive

SYNOPSIS

       grub-install [OPTION] install_device

DESCRIPTION

       Install GRUB on your drive.

       -h, --help
	      print this message and exit

       -v, --version
	      print the version information and exit

       --root-directory=DIR
	      install GRUB images under the directory DIR instead of the root directory

       --grub-shell=FILE
	      use FILE as the grub shell

       --no-floppy
	      do not probe any floppy drive

       --force-lba
	      force GRUB to use LBA mode even for a buggy BIOS

       --recheck
	      probe a device map even if it already exists

       INSTALL_DEVICE can be a GRUB device name or a system device filename.

       grub-install  copies GRUB images into the DIR/boot directory specfied by --root-directory, and uses the grub shell to install grub into the
       boot sector.

       The grub source distribution carries this script to ease the installation of grub as a boot loader. In Suse Linux however,  grub  installa-
       tion  is  much  better handled by Yast; use of this script is generally discouraged and therefore unsupported. Consequently, the script has
       been renamed to grub-install.unsupported.

       In order to (re-)install grub for the currently running system, simply use Yast. For an installation aiming  at	a  differing  system,  the
       crafting  of an appropriate device.map and grub shell script is strongly advised, e.g.  "grub --batch --device-map=target-device.map < tar-
       get-grub.conf"

SEE ALSO

       The full documentation for grub-install is maintained as a Texinfo manual.  If the info and grub-install programs are properly installed at
       your site, the command

	      info grub-install

       should give you access to the complete manual.
