Git Cheat Sheet
For a while now, I’ve had a gradually-expanding note with various git commands that I’ve been using as a cheat sheet for git tasks that I do not do often, but regularly enough to write them down.
I figure putting them here will not only make them (slightly) easier to get to every time, but may also help other folks out.
So here they are! Keep in mind that this is just a quick (and intentionally incomplete) cheat sheet – if you are learning git for the first time, you’re better off looking elsewhere this is a good place to start.
General
Delete a file from the repo (opposite of ‘git add’):
git rm filename
revert a file to the current committed version:
git checkout -- filename
cache credentials when using https (seconds):
git config credential.helper 'cache --timeout=300'
clear cached credentials:
git credential-cache exit
ignore changes to a versioned file:
git update-index --assume-unchanged <file>
stop ignoring those changes:
git update-index --no-assume-unchanged <file>
change commit message of last commit:
git commit --amend -m "New commit message"
Branches
See all branches, including remote branches:
git branch -a
Pull a branch from a remote (“origin” here) and track it (this is tested and works with git 1.7.2.3 and higher)
git fetch --all
git checkout -b branch_name origin/branch_name
push a new local branch to origin:
git push -u origin branch-name
create a new branch:
git checkout -b new_branch
merge changes from branch hotfix into master:
git checkout master
git merge hotfix
delete the local branch:
git branch -d hotfix
track a remote branch:
git branch --set-upstream krystof_plots origin/krystof_plots
Tags
create a tag and push it to origin:
git tag -a v1.4 -m 'my version 1.4'
git push origin --tags
pull tags:
git pull --tags
find out what tag you’re on:
git describe --tags
Forks
Add upstream remote:
git remote add upstream git@github.com:krystofl/krystof-utils.git
sync a fork (https://help.github.com/articles/syncing-a-fork):
git fetch upstream
git checkout master
git merge upstream/master
Reset a fork to whatever is on upstream:
git fetch upstream
git checkout master
git reset --hard upstream/master
git push origin master --force
Submodules
Add a git repo as a submodule:
git submodule add https://github.com/krystofl/krystof-utils.git
To make the submodule track a the master branch: open .gitmodules
, and add a line to the submodule info:
branch = master
Move a submodule:
git mv path/to/old/submod path/to/new/submod
Remove a submodule (works most of the time):
git rm path/to/submodule
If the above doesn’t work, see this StackOverflow answer.
