Workspace tips

  • Show branch in prompt
PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\[\033[01;33m\]`git branch 2>/dev/null|cut -f2 -d\* -s|sed -e"s/ //g"`\[\033[00m\]\$ '
  • gitk is a great tool for visualizing the git history and seeing where your master or branch is wrt origin:master

  • git gui is a great tool for performing git commands with a graphical user interface

Stash local changes temporarily

  • git stash

Create a local branch

  • git branch test

Swtich to a local branch

  • git checkout test

Get stashed local changes

  • git stash pop

Update a branch to the remote master's head

  • git stash
  • git rebase origin master
  • git stash pop

Stash only those changes that have not been staged

  • git stash save --keep-index

Add to local commit

  • git add <filename>
  • git add -A

Push local commit

  • git push origin master

Remove a local branch

  • git checkout master
  • git branch -d <branch>

Track a remote branch

  • "git fetch" (get up to date) or "git pull"
  • git branch --track somebranch origin/somebranch
    • --track is not needed unless you've set branch.autosetupmerge to false in your config
  • git checkout somebranch
  • git commit
  • git push
    • sends changes to origin/somebranch

Delete a remote branch

  • Don't do this unless you're incredibly confident in what you're doing
  • git push origin :somebranch

Project History

  • git log ( To view the history of your changes )
  • git log -p ( To see complete diffs at each step )
  • git log --stat --summary ( To see overview )

Setting up tracked repositories to start pushing

  1. If you have cloned read-only version, do the following first
    1. git remote rm origin
  2. Add the proper remote
    1. git remote add origin git@gitorious.org:tubetk/tubetk.git
  3. You can push your changes
    1. git push origin master

Use a global ignore file for editor backups

Different developers' editors use different backup file names. Rather than put every possible editor backup file name in every project .gitignore, use a personal gitignore file to ignore your own editor backup files:

git config --global core.excludesfile ~/.gitignore
echo '*~' >> ~/.gitignore

Now, the exclusion pattern '*~' will be applied in every directory of every git project you use.

View history

Take a look at the history:

git log -C --stat

(git log has a bunch of options; this set detects renames and copies, and shows a summary of what files are changed in each commit) Get a closer look at a particular change by commit:

git log -C -p -1 57c609

(-p shows a patch, -1 restricts to a single change, and 57c609 is the start of a commit shown by the first 'git log' command) Get a list of commits to a particular file since vBeta branch:

git log --oneline vBeta..origin/v1.0 -- CMakeLists.txt

View history graphically, if you installed the necessary program:

gitk --all
qgit --all

You can also [view the history online in gitorious/github], but viewing the history locally is often more powerful.

View commits affecting a certain file only:

git whatchanged filename
