Question

I'm looking at a git hook which looks for print statements in Python code. If a print statement is found, it prevents the git commit.

I want to override this hook and I was told that there is a command to do so. I haven't been able to find it. Any thoughts?

Accepted Answer

Maybe (from git commit man page):

git commit --no-verify -m "commit message"
           ^^^^^^^^^^^
-n  
--no-verify

This option bypasses the pre-commit and commit-msg hooks. See also githooks(5).

As commented by Blaise, -n can have a different role for certain commands.
For instance, git push -n is actually a dry-run push.
Only git push --no-verify would skip the hook.

Note: Git 2.14.x/2.15 improves the --no-verify behavior:

commit: skip discarding the index if there is no pre-commit hook

"git commit" used to discard the index and re-read from the filesystem just in case the pre-commit hook has updated it in the middle; this has been optimized out when we know we do not run the pre-commit hook.

Davi Lima points out in the comments the git cherry-pick does not support --no-verify.
So if a cherry-pick triggers a pre-commit hook, you might, as in this blog post, have to comment/disable somehow that hook in order for your git cherry-pick to proceed.

The same process would be necessary in case of a git rebase --continue, after a merge conflict resolution.

With Git 2.36 (Q2 2022), the callers of run_commit_hook() to learn if it got "success" because the hook succeeded or because there wasn't any hook.
