work with github

git clone                       //clone others git repository
git clone -b <branch> <remote_repo>         //clone a single branch

git remote add origin https://github.com/dongdongbh/Test.git
git remote -v                       //look up remote repository
git pull origin master --allow-unrelated-histories
git push origin master

//push to two repository
$git remote add all git@git.coding.net:user/project.git
$git remote set-url --add --push all git@git.coding.net:user/project.git
$git remote set-url --add --push all git@github.com:user/repo.git
git push all master

git fetch --all


git branch local                    //add branch
git checkout -b local_2                 //add branch and switch to it
git branch                      //show branches

git checkout --orphan <branchname>  //create a empty branch

git checkout local                  //switch to branch
git commit -a -m 'branch update'            //commit all tracking file
git push origin local                   //add local branch to remote server

git fetch origin                //get remote branch(that exists only on the remote, but not locally)
git checkout --track origin/<remote_branch_name>

git push origin --delete {the_remote_branch}         //delete remote branch
git branch --set-upstream-to=origin/master master     //tracking remote master
git branch -vv                      //check remote master
git branch -d local_2
git push origin :Local                  //delete Local branch from remote server


git diff                    //diff between working tree and staging area
git diff --staged               //diff between staging area and last commit
git checkout master         
git merge local_2

git merge origin/master             //merge with remote branch
git mergetool


git checkout -- file-name               //reset file from stage area to working tree
git checkout hash_id -- file            //reset file from specific commit to working tree and staging area
git reset HEAD file-name            //reset file from commit to stage area

git push -f origin master			//force push local to remote, some dangerous

git reset --hard HEAD^              //reset the last vision
git reset --hard    ID          //ID is vision ID, and change to the vision     
git reset --hard origin/master          //reset to remote master
git reset --hard origin/master          //use this two command to replace the local by remote

git commit --amend 						//modify commit message

diff & patch

git diff [options] [<commit>] [--] [<path>…​]
$ git diff            //diff not staged file with last commit
$ git diff --cached   //diff for staged file with last commit
$ git diff [branch]  //show diff with other branch

$ git diff --name-only //only show file name of diff
$ git diff --shortstat

git diff from-commit to-commit > output-file

git apply patch.diff


set remote module repositoryS as a subtree of project repositoryA

git remote add xxx(remote submodule repositoryS) github_remote_address
git subtree add --prefix=local_dir xxx master 
git subtree pull --prefix=local_dir xxx master      //pull from remote module repositoryS
git subtree push --prefix=local_dir xxx master      //push to remote module repositoryS
git push origin master                  //push to the project repositoryA

merge and rebase

git merge --squash another_branch       //merge another branch but delete the commits on that branch
git commit -m "xxxxxx"              //add commit to this merge work

git rebase another_branch           //re-base current branch to another branch  
git checkout another_branch                 
git merge rebased_branch            //merge re-based branch (fast forward). to achieve a clear history

change history tree

git commit --amend --no-edit // add changes to last commit without new commit
git rebase -i // modify commit history interactively
