# BASIC COMMAND …
## note: command with slash ‘/’ in between can be optionally chosen, eg:
-s/-b, you can choose either –s or –b
→ git init # to initialize a git repo
… hardcore hacking …
→ git status –s/–b/-sb # show file added to staging area, files with
changes, untracked files
→ git log hai.txt # show recent commits on hai.txt
→ git add ./–A/[file/files] # adding file(s) to index
→ git commit –m “commit message” # message of a commit
### working remotely
→ git remote add/delete [remote.name] [git.url] # adding/deleting remote
→ git push [remote.name] [branch.name] # update the [remote] with your
commit from [branch.name]
→ git pull # fetch changes from remote and merge into current branch
→ git fetch [remote.name] # update the remote-tracking branch for
[remote.name] (default is origin)

# EVEN MORE COMMAND …
## note: HEAD === most recent commit on your working branch. As I said
before, default is master.
→ git add [dir] # add all files in [dir] directory
→ git add .
### add all files under current directory, untracked file included
→ git rm [file1] [files2] … [fileN] # remove n files from the project
→ git reset HEAD [file] # remove specified file from next commit
### branching
→ git checkout –b [branch.name] # create a new branch and switch to it
→ git branch –d [branch.name] # delete a branch
→ git rev-parse HEAD # show me SHA of last commit
→ git cat-file –t HEAD # what type of last commit in current working
branch
→ git cat-file –p HEAD # all your last commit’s information belong to
us ;)
→ git clone # clone a repo
