Desfazendo um git push

Não é possível desfazer um push diretamente, como é feito com o commit utilizando o comando $ git reset --soft|mixed|hard hash-do-penultimo-commit

Para desfazer um push são necessários 3 passos:

Utilizar o comando $ git reset --mixed HEAD~1 e em seguida utilizar o comando $ git stash (se preferir pode usar a opção -m "revertendo o push blablabla" para salvar o stash com um contexto do que foi feito
Utilizar o comando $ git revert HEAD~0
Utilizar o comando $ git stash apply
Utilizar o comando $ git push origin sua-branch -f

	# Use-case:
	# - We have multiple git repositories but want to merge them together for simplicity / using a monorepo / etc.
	# - We can not lose the git history and tags
	# - The new structure can be arbitrary
	#
	# Solution:
	# - Create a tmp directory and clone all previous repos
	# - Install git filter-repo via pip
	# - In each of these repos, use the git filter-repo command to move all files to any new directory inside the repository
	# - cd anywhere and create your new repository

	# By default, desktop environment won't start unless you connect your monitor
	# This config allows you to start desktop environment and enable GPU acceleration without monitor connected. Official Nvidia driver is required if you use Nvidia card.
	# NO DUMMY DISPLAY PLUGS REQUIRED
	# Save the file to /etc/X11/xorg.conf
	# Disable "Allow Flipping" in Nvidia settings to fix desktop flickering

	# Tested on Linux Mint 21 with AnyDesk remote desktop
	# GPU: NVIDIA GeForce GT 710

	# nvidia-xconfig: X configuration file generated by nvidia-xconfig

	# This xorg configuration file will start a dummy X11 server.
	# move it to /etc/X11/xorg.conf
	# don't forget apt install xserver-xorg-video-dummy;
