How do I sync two local file structures

I have two large source trees. One of them has some out of date image files. I would like to automatically update all the old image files (png, jpg, gif) in one source tree with the up to date image files in the other source tree.

I am using Windows 7 but I have Cygwin installed. I have tried using rsync so far but with no success.

I was hoping I could do something like:

rsync -r *.png newSourceTree oldSourceTree

If there is some other way of achieving the same thing e.g. a Perl or Bash script, I'd be open to using that too.

Any help would be much appreciated.

Thanks, James.

Unison is designed for exactly this sort of problem. You can synchronize all the files using

unison oldTree newTree -force newer

If you want it to touch only image files, read the documentation.

You want:

rsync -av --include '*.png' --include '*/' --exclude '*' newSourceTree/ oldSourceTree/

A quick explanation: You want to include png files, include all directories (so that it can recurse), then exclude everything else. Include/Exclude are processed left to right, and default to including everything.

What about:

robocopy c:\source\ c:\destination\ *.png *.gif /s
