How to copy only modified files between two directories

[guarriman]

Hi.

I've got two directories ('original' and 'copy') with subdirectories inside and I edit files within 'original'.

I want to copy *only* modified files of 'original' into 'copy'. Which is the best way to do this with shell commands?

Thank you very much.

You might also consider looking at rsync, which is probably one of the most useful tools in the universe. Well, it's pretty useful anyway.
