  Git

  I prefer to use the git command line to control my repo instead of a git GUI tool.

• Prevent your git graph from merging together and avoid committing after you send the CLI.

git merge --no-ff --no-commit hash

• Edit your commit

`git commit --amend`

• Rebase and sync your local repo with remote

`git pull origin --rebase`

• Store/Recover/Show your unfinished work

git stash --include-untracked 、 git stash pop、 git list

• See your local git info

`git config -l`

• Basic git concepts

`git add , git commit , git push , git checkout, git pull , git cherry-pick, git branch , git remote...etc.`
