Apply multiple .patch files

Question

I have a directory with .patch files, generated using diff.

I would like to apply all those patches using patch -p1 to another directory.

But patch takes only one file, unless I cat.

What would the command be to apply multiple files using xargs or a similar tool.

Answer 1

If cat works, why not use it?

To use find and xargs:

find dirname -name namespec -print 0 | xargs -0 patch patchargs

Answer 2

Assuming you're using bash/sh/zsh etc...

cd /path/to/source
for i in /path/to/patches/*.patch; do patch -p1 < $i; done
