Want a linear git history? Github has a button for you: "Rebase and Merge". You can even disable all the other merge buttons and force its use!

Problem is, Github is not particularly smart about how it does this. In particular, if you have signed commits and your branch is showing up proud and verified, your main will still have unverified commits. Github really means rebase, in that case, even when git merge --ff-only would do the job.

With this tool you have a "merge button" which you can run to merge a PR from the command line, preserving both linear history and your signed commits.

This tool will fail unless both git and gh are installed, available on the PATH, and configured appropriately.
