While I was working on the previous post I accidentally messed up half of the files that I was trying to fix. I had one copy of the file and I needed to copy it to the original files. cp support copying multiple files to the same location but not the reverse so I had to rely on something else.

The line below will copy one file to multiple locations when the original file still exists:

find . -name FileName.php | grep library | xargs -n 1 cp /path/to/original/FileName.php

As always with posts that could mess up data, I take no responsibility for any lost data. I suggest you run this on a single file first to make sure it doesn’t have any unattended consequences and backup anything that’s going to be changed.
