My Solution
Hi guys,

Thanks for your help.

Here's my solution, which is not very elegant. I've run the sed 4 times. The reason I've done it this way is I can avoid any problems with odd xml characters such as < /. Also the problem where I want change 256 to 512 then 128 to 256 I think needs to be done in a specific order. I saved this below in a file called Replacer.sh.

Code:
#!/bin/sh

cat filename$1.tmx|sed 's/"32"/"64"/g' > filename$1-suffix.tmx
cat filename$1-suffix.tmx|sed 's/"256"/"512"/g' > filename$1-suffix.tmx
cat filename$1-suffix.tmx|sed 's/"128"/"256"/g' > filename$1-suffix.tmx
cat filename$1-suffix.tmx|sed 's/imageName.png/imageName-suffix.png/g' > filename$1-suffix.tmx

Then to run it I call
Code:
sh Replacer.sh 1

and
Code:
sh Replacer.sh 2

etc.

I know I can run it all as a loop but at the moment I want to run it on one file at a time and test that file in my other program.

The only other issue is I don't think I can overwrite the suffix file if it already exists. No doubt there is a command to overwrite, but i couldn't find it.

You might have guessed from the .tmx these are tilemaps that need a low res and high res version.

dirname

BASENAME(1)						    BSD General Commands Manual 					       BASENAME(1)

NAME

     basename, dirname -- return filename or directory portion of pathname

SYNOPSIS

     basename string [suffix]
     basename [-a] [-s suffix] string [...]
     dirname string

DESCRIPTION

     The basename utility deletes any prefix ending with the last slash '/' character present in string (after first stripping trailing slashes),
     and a suffix, if given.  The suffix is not stripped if it is identical to the remaining characters in string.  The resulting filename is
     written to the standard output.  A non-existent suffix is ignored.  If -a is specified, then every argument is treated as a string as if
     basename were invoked with just one argument.  If -s is specified, then the suffix is taken as its argument, and all other arguments are
     treated as a string.

     The dirname utility deletes the filename portion, beginning with the last slash '/' character to the end of string (after first stripping
     trailing slashes), and writes the result to the standard output.

EXAMPLES

     The following line sets the shell variable FOO to /usr/bin.

	   FOO=`dirname /usr/bin/trail`

DIAGNOSTICS

     The basename and dirname utilities exit 0 on success, and >0 if an error occurs.

SEE ALSO

     csh(1), sh(1)

STANDARDS

     The basename and dirname utilities are expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
