git format-patch

Prepare .patch files. Useful when emailing commits elsewhere. See also git am, which can apply generated .patch files. More information: https://git-scm.com/docs/git-format-patch.

• Create an auto-named .patch file for all the unpushed commits:

git format-patch {{origin}}

• Write a .patch file for all the commits between 2 revisions to stdout:

git format-patch {{revision_1}}..{{revision_2}}

• Write a .patch file for the 3 latest commits:

git format-patch -{{3}}
