[nzlug] diffmerge

[Johann Schoonees]

Hi

Anyone know of a tool that merges files from one or more directories 
to a destination directory, based on diff(1) or cmp(1) instead of 
filenames?

diffmerge [options] target_dir [target_dir ...] dest_dir

Creates dest_dir if it does not exist.  Any existing dest_dir need not 
be empty but its files will not be mutually compared for uniqueness.

Options might be:
     -A   Include hidden files
     -R   Recurse through target_dir[s]

Some arbitrary rules may have to be made, such as:
If two files compare successfully (whether their filenames agree or 
not), only the older one is copied to dest_dir.
If two files differ but have the same name, add a unique suffix to the 
newer one.

No luck with google.  I'm about to start writing a bash script but 
someone might save me a lot of time.

Johann
