git

The list of helpful git commands was growing too large, so compiling into one page.

git fetch origin <REMOTE_BRANCH>:<LOCAL_BRANCH>

Pull all changes:

git pull --recurse-submodules

Reset changes to submodules (including fast-forwards):

git submodule deinit -f .
git submodule update --init

# From old page

• Change local username / email: git config user.email [EMAIL] or user.name [NAME]
• Change default editor: git config --global core.editor vim

• Reset author: git commit --amend --reset-author --no-edit
• Set author: git commit --amend --author "[NAME] <[EMAIL]>" --no-edit
• Clean all: git reset --hard && git clean -dfx

• Create a patch: git diff > [FILE]
• Apply a patch: git apply --whitespace=fix --reject [FILE]
• Apply rejected patches: wiggle --replace [FILE] [FILE.rej]

• Interactive add: git add -p .
• Rebase:
  • git rebase --committer-date-is-author-date --rebase-merges -i [COMMIT]~
  • Change pick to edit
  • git add and git commit --amend
  • git rebase --continue
• Insert changes to previous commits:
  • git commit --fixup=[COMMIT]
  • git stash
  • git rebase -i --autosquash [COMMIT]^
  • git stash pop
• Enable autosquashing by default: git config --global rebase.autoSquash true
• Cherry pick commits:
  • git switch -c [BRANCH]
  • git cherry-pick -x [COMMIT]
  • git push --set-upstream origin [BRANCH]

By default, GPG keys are used for signing commits (manually using -S flag). As of Git 2.34 (Nov 2021), SSH keys can also be used to sign commits.

• Enable commit signing: git config --global commit.gpgsign true
• Use SSH key for signing: git config --global gpg.format ssh
• Specify signing key (GPG/SSH): git config --global user.signingkey [PUB_KEY]
• Verify commit has been signed: git log --show-signature ("No signature" for SSH)

• Beautify git log: git config --global alias.adog "log --all --decorate --oneline --graph"
• Check branches with latest commits: git branch -a --sort=-committerdate
• Manually delete detached commits (warning! stashes will be deleted): git reflog expire --expire-unreachable=now --all && git gc --prune=now
• Subversion integration: apt install git-svn
• History: gitk
• Push to multiple remotes (and fetch only from one):
  • git remote add all GITREPO1 (sets fetch)
  • git remote set-url --add --push all GITREPO1 (overrides push)
  • git remote set-url --add --push all GITREPO2 (appends push)
  • git push -u all main (set upstream to all)
