## Generate a patch from un-commited files:
`git diff > file.patch`

But sometimes it happens that part of the stuff you're doing are new files that are untracked and won't be in your git diff output. So, one way to do a patch is to stage everything for a new commit (but don't do the commit), and then:

`git diff --cached > file.patch`

Add the 'binary' option if you want to add binary files to the patch (e.g. mp3 files):

`git diff --cached --binary > file.patch`

## Generate a patch between two commits
`git diff commitid1 commitid2 > file.patch`

## Generate a patch between the HEAD and a specific commits
`git diff commitid1 > file.patch`

## Generating a patch from excluded files
`diff -u path/to/file path/to/new/file > file.patch`

## Generate a patch from git stash
`git stash show -p > file.patch`

## Apply the patch:
`git apply mypatch.patch`
