I need to get patch file for inital commit (which is not empty) for our review process, but I'm confused as git format-patch command only makes it from branch that is on initial commit not including it.

Seems it must be some obvious move but I'm completely missing it.

Try git format-patch --root $SHA (where $SHA is that first commit)

    It works for getting a patch file from the first commit only. when getting patch files from all history, it requires two steps: 1) get a patch file from the initial commit, apply it. then gets patch files by running `git format-patch ${SHA1_of_initial_commit)..HEAD`, apply them. – shawnzhu May 02 '18 at 19:09

for making patch for a single commit just use

git format-patch -1 HEAD # where "1" is a number, not "ell".

where "HEAD" could be changed to any other commit, or even hash code. This works even if HEAD is the first commit. I am not sure whether you are asking for this.

Maybe this has changed, but

git format-patch --root

just created all patch files including the initial commit and HEAD. My git version is 2.26.2.windows.1.
