Please post an example of both files where we can see by which key/criteria the replacement should be done.
Please use [code] and [/code] tags for better readability of the examples, thanks.
@pamu:
You can leave that cat out. It is not needed since sed like many other tools can read files on their own; example:

XDIFF_FILE_RABDIFF(3) 1 XDIFF_FILE_RABDIFF(3)xdiff_file_rabdiff - Make binary diff of two files using the Rabin's polynomial fingerprinting algorithmSYNOPSIS
bool xdiff_file_rabdiff (string $old_file, string $new_file, string $dest)
DESCRIPTION
Makes a binary diff of two files and stores the result in a patch file. The difference between this function and xdiff_file_bdiff(3) is
different algorithm used which should result in faster execution and smaller diff produced. This function works with both text and binary
files. Resulting patch file can be later applied using xdiff_file_bpatch(3)/xdiff_string_bpatch(3).
For more details about differences between algorithm used please check libxdiff website.
PARAMETERS
o $old_file
- Path to the first file. This file acts as "old" file.
o $new_file
- Path to the second file. This file acts as "new" file.
o $dest
- Path of the resulting patch file. Resulting file contains differences between "old" and "new" files. It is in binary format and
is human-unreadable.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
xdiff_file_rabdiff(3) example
The following code makes binary diff of two archives.
<?php
$old_version = 'my_script_1.0.tgz';
$new_version = 'my_script_1.1.tgz';
xdiff_file_rabdiff($old_version, $new_version, 'my_script.bdiff');
?>
NOTES
Note
Both files will be loaded into memory so ensure that your memory_limit is set high enough.
