=== 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 ===
#If you have cloned read-only version, do the following first
## git remote rm origin
# Add the proper remote
##git remote add origin
# You can push your changes
##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
