Configuration Files
Repository specific configuration file [--local]:
<repo>/.git/config
User-specific configuration file [--global]:
~/.gitconfig
System-wide configuration file [--system]:
/etc/gitconfig
Create
Clone an existing repository:
There are two ways:
Via SSH
$ git clone ssh://user@domain.com/repo.git
Via HTTP
$ git clone http://domain.com/user/repo.git
Create a new local repository in the current directory:
$ git init
Create a new local repository in a specific directory:
$ git init <directory>
Local Changes
Changes in working directory:
$ git status
Changes to tracked files:
$ git diff
See changes/difference of a specific file:
$ git diff <file>
Add all current changes to the next commit:
$ git add .
Add some changes in <file> to the next commit:
$ git add -p <file>
Add only the mentioned files to the next commit:
$ git add <filename1> <filename2>
Commit all local changes in tracked files:
$ git commit -a
Commit previously staged changes:
$ git commit
Commit with message:
$ git commit -m 'message here'
Commit skipping the staging area and adding message:
$ git commit -am 'message here'
Commit to some previous date:
$ git commit --date="`date --date='n day ago'`" -am "<Commit Message Here>"
Change last commit:
Don't amend published commits!
$ git commit -a --amend
Amend with last commit but use the previous commit log message
Don't amend published commits!
$ git commit --amend --no-edit
Change committer date of last commit:
GIT_COMMITTER_DATE="date" git commit --amend
Change Author date of last commit:
$ git commit --amend --date="date"
Move uncommitted changes from current branch to some other branch:
$ git stash
$ git checkout branch2
$ git stash pop
Restore stashed changes back to current branch:
$ git stash apply
Restore particular stash back to current branch:
- {stash_number} can be obtained from
git stash list
$ git stash apply stash@{stash_number}
Remove the last set of stashed changes:
$ git stash drop
Search
A text search on all files in the directory:
$ git grep "Hello"
In any version of a text search:
$ git grep "Hello" v2.5
Show commits that introduced a specific keyword
$ git log -S 'keyword'
Show commits that introduced a specific keyword (using a regular expression)
$ git log -S 'keyword' --pickaxe-regex
Commit History
Show all commits, starting with newest (it'll show the hash, author information, date of commit and title of the commit):
$ git log
Show all the commits(it'll show just the commit hash and the commit message):
$ git log --oneline
Show all commits of a specific user:
$ git log --author="username"
Show changes over time for a specific file:
$ git log -p <file>
Display commits that are present only in remote/branch in right side
$ git log --oneline <origin/master>..<remote/master> --left-right
Who changed, what and when in <file>:
$ git blame <file>
Show Reference log:
$ git reflog show
Delete Reference log:
$ git reflog delete
Move or Rename
Rename a file:
Rename Index.txt to Index.html
$ git mv Index.txt Index.html
Branches and Tags
List all local branches:
$ git branch
List local/remote branches
$ git branch -a
List all remote branches:
$ git branch -r
Switch HEAD branch:
$ git checkout <branch>
Checkout single file from different branch
$ git checkout <branch> -- <filename>
Create and switch new branch:
$ git checkout -b <branch>
Switch to the previous branch, without saying the name explicitly:
$ git checkout -
Create a new branch from an exiting branch and switch to new branch:
$ git checkout -b <new_branch> <existing_branch>
Checkout and create a new branch from existing commit
$ git checkout <commit-hash> -b <new_branch_name>
Create a new branch based on your current HEAD:
$ git branch <new-branch>
Create a new tracking branch based on a remote branch:
$ git branch --track <new-branch> <remote-branch>
Delete a local branch:
$ git branch -d <branch>
Rename current branch to new branch name
$ git branch -m <new_branch_name>
Force delete a local branch:
You will lose unmerged changes!
$ git branch -D <branch>
Mark HEAD
with a tag:
$ git tag <tag-name>
Mark HEAD
with a tag and open the editor to include a message:
$ git tag -a <tag-name>
Mark HEAD
with a tag that includes a message:
$ git tag <tag-name> -am 'message here'
List all tags:
$ git tag
List all tags with their messages (tag message or commit message if tag has no message):
$ git tag -n
Update and Publish
List all current configured remotes:
$ git remote -v
Show information about a remote:
$ git remote show <remote>
Add new remote repository, named <remote>:
$ git remote add <remote> <url>
Rename a remote repository, from <remote> to <new_remote>:
$ git remote rename <remote> <new_remote>
Remove a remote:
$ git remote rm <remote>
Note: git remote rm does not delete the remote repository from the server. It simply removes the remote and its references from your local repository.
Download all changes from <remote>, but don't integrate into HEAD:
$ git fetch <remote>
Download changes and directly merge/integrate into HEAD:
$ git remote pull <remote> <url>
Get all changes from HEAD to local repository:
$ git pull origin master
Get all changes from HEAD to local repository without a merge:
$ git pull --rebase <remote> <branch>
Publish local changes on a remote:
$ git push remote <remote> <branch>
Delete a branch on the remote:
$ git push <remote> :<branch> (since Git v1.5.0)
OR
$ git push <remote> --delete <branch> (since Git v1.7.0)
Publish your tags:
$ git push --tags
Configure the merge tool globally to meld (editor)
$ git config --global merge.tool meld
Use your configured merge tool to solve conflicts:
$ git mergetool
Merge and Rebase
Merge branch into your current HEAD:
$ git merge <branch>
List merged branches
$ git branch --merged
Rebase your current HEAD onto <branch>:
Don't rebase published commit!
$ git rebase <branch>
Abort a rebase:
$ git rebase --abort
Continue a rebase after resolving conflicts:
$ git rebase --continue
Use your editor to manually solve conflicts and (after resolving) mark file as resolved:
$ git add <resolved-file>
$ git rm <resolved-file>
Squashing commits:
$ git rebase -i <commit-just-before-first>
Now replace this,
pick <commit_id>
pick <commit_id2>
pick <commit_id3>
to this,
pick <commit_id>
squash <commit_id2>
squash <commit_id3>
Undo
Discard all local changes in your working directory:
$ git reset --hard HEAD
Get all the files out of the staging area(i.e. undo the last git add
):
$ git reset HEAD
Discard local changes in a specific file:
$ git checkout HEAD <file>
Revert a commit (by producing a new commit with contrary changes):
$ git revert <commit>
Reset your HEAD pointer to a previous commit and discard all changes since then:
$ git reset --hard <commit>
Reset your HEAD pointer to a remote branch current state.
$ git reset --hard <remote/branch> e.g., upstream/master, origin/my-feature
Reset your HEAD pointer to a previous commit and preserve all changes as unstaged changes:
$ git reset <commit>
Reset your HEAD pointer to a previous commit and preserve uncommitted local changes:
$ git reset --keep <commit>
Remove files that were accidentally committed before they were added to .gitignore
$ git rm -r --cached .
$ git add .
$ git commit -m "remove xyz file"
