Note: .git/config must have a [branch "some_name"] section for the current branch, to know which remote-tracking branch to merge into the current branch. Git 1.5.3 and above adds this automatically. git push update the server with your commits across all branches that are *COMMON* between your local copy and the server. Local branches that were never pushed to the server in the first place are not shared. git push origin <branch> update the server with your commits made to <branch> since your last push. This is always *required* for new branches that you wish to share. After the first explicit push, "git push" by itself is sufficient. git push origin <branch>:refs/heads/<branch> E.g. git push origin twitter-experiment:refs/heads/twitter-experiment Which, in fact, is the same as git push origin <branch> but a little more obvious what is happening. Reverting --------- git revert <rev> reverse commit specified by <rev> and commit the result. This does *not* do the same thing as similarly named commands in other VCS's such as "svn revert" or "bzr revert", see below git checkout <file> re-checkout <file>, overwriting any local changes git checkout . re-checkout all files, overwriting any local changes. This is most similar to "svn revert" if you're used to Subversion commands revert a merge commit: git revert -m 1 sha Fix mistakes / Undo ------------------- git reset --hard abandon everything since your last commit; this command can be DANGEROUS. If merging has resulted in conflicts and you'd like to just forget about the merge, this command will do that. git reset --hard ORIG_HEAD undo your most recent *successful* merge *and* any changes that occurred after. Useful for forgetting about the merge you just did. If there are conflicts (the merge was not successful), use "git reset --hard" (above) instead. git reset --soft HEAD^ forgot something in your last commit? That's easy to fix. Undo your last commit, but keep the changes in the staging area for editing. git commit --amend redo previous commit, including changes you've staged in the meantime. Also used to edit commit message of previous commit. Plumbing -------- test <sha1-A> = $(git merge-base <sha1-A> <sha1-B>) determine if merging sha1-B into sha1-A is achievable as a fast forward; non-zero exit status is false. Stashing -------- git stash save <optional-name> save your local modifications to a new stash (so you can for example "git svn rebase" or "git pull") git stash apply restore the changes recorded in the stash on top of the current working tree state git stash pop restore the changes from the most recent stash, and remove it from the stack of stashed changes git stash list list all current stashes git stash show <stash-name> -p show the contents of a stash - accepts all diff args git stash clear delete current stashes Remotes ------- git remote add <remote> <remote_URL> adds a remote repository to your git config. Can be then fetched locally. Example: git remote add coreteam git://github.com/wycats/merb-plugins.git git fetch coreteam git push <remote> :refs/heads/<branch> delete a branch in a remote repository git push <remote> <remote>:refs/heads/<remote_branch> create a branch on a remote repository Example: git push origin origin:refs/heads/new_feature_name git push <repository> +<remote>:<new_remote> create a branch on a remote repository based on +<remote> Example: git push origin +master:my_branch git remote prune <remote> prune deleted remote-tracking branches from "git branch -r" listing git remote add -t master -m master origin git://example.com/git.git/ add a remote and track its master git remote show <remote> show information about the remote server. git checkout -b <local branch> <remote>/<remote branch> Eg git checkout -b myfeature origin/myfeature Track a remote branch as a local branch. git pull <remote> <branch> git push For branches that are remotely tracked (via git push) but that complain about non-fast forward commits when doing a git push. The pull synchronizes local and remote, and if all goes well, the result is pushable. Submodules ---------- git submodule add <remote_repository> <path/to/submodule> add the given repository at the given path. The addition will be part of the next commit. git submodule update [--init] Update the registered submodules (clone missing submodules, and checkout the commit specified by the super-repo). --init is needed the first time. git submodule foreach <command> Executes the given command within each checked out submodule. Remove submodules 1. Delete the relevant line from the .gitmodules file. 2. Delete the relevant section from .git/config. 3. Run git rm --cached path_to_submodule (no trailing slash). 4. Commit and delete the now untracked submodule files. pull all git submodule foreach 'git pull origin master' Git Instaweb ------------ git instaweb --httpd=webrick [--start | --stop | --restart] Environment Variables --------------------- GIT_AUTHOR_NAME, GIT_COMMITTER_NAME Your full name to be recorded in any newly created commits. Overrides user.name in .git/config GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL Your email address to be recorded in any newly created commits. Overrides user.email in .git/config GIT_DIR Location of the repository to use (for out of working directory repositories) GIT_WORKING_TREE Location of the Working Directory - use with GIT_DIR to specifiy the working directory root or to work without being in the working directory at all.
