If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

Generate and add your key to GitHub
$ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
$ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
$ git config --global alias.logs "log --show-signature" (now available as $ git logs)
$ git config --global alias.cis "commit -S" (optional if global signing is false)
$ echo "Some content" >> example.txt
$ git add example.txt
$ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

1 - install GPG tools : https://gpgtools.org/

2 - Create new key for your github email

3 - Add key to git on your local machine: git config --global user.signingkey YOURKEY

4 - configure git to sign all commits: git config --global commit.gpgsign true

5 - add to the bottom of ~/.gnupg/gpg.conf: (create the file if it not exists)

How to change your commit messages in Git?

At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.

Not pushed + most recent commit:

git commit --amend

This will open your $EDITOR and let you change the message. Continue with your usual git push origin master.

	# alias to edit commit messages without using rebase interactive
	# example: git reword commithash message
	reword = "!f() {\n GIT_SEQUENCE_EDITOR=\"sed -i 1s/^pick/reword/\" GIT_EDITOR=\"printf \\\"%s\\n\\\" \\\"$2\\\" >\" git rebase -i \"$1^\";\n git push -f;\n}; f"

	# sort list of git repos with gh cli
	gh repo list --limit 300 --json name -q '.[].name' \| sort

	# count total commits in a repo
	git rev-list --all --count

	if (in_array($dataFinal->format('w'), array(0,6))) {
	continue;
	}
	$diasParaSomar--;
