rebase --no-verify

rebase --no-verify

It is sometimes desirable to disable the safety net of pre-rebase hook
when the user knows what he is doing (for example, when the original
changes on the branch have not been shown to the public yet).

This teaches --no-verify option to git-rebase, which is similar to the way
pre-commit hook is bypassed by git-commit.
