Git is software that records changes to files over time. This concept is also known as version control. These recorded changes allow you to recall specific versions of the files at a later date.
Commands for your own project:
git init // create new repo
git status // show which files are changed and which of them are staged
git add -p // add “chunks” of changed files to the stage
git commit -m "<commit message>" // commit everything added to the stage with a commit message
git log // show a list of commits
git checkout <file> // throw away all changes since the last commit (one file)
git reset --hard // throw away all changes since the last commit (all files)
Commands for your someone else’s project:
git clone <repo_url> <target_dir> // clone a remote repository locallygit pull // download and merge new commits in the remote repo that happened since the last clone/pullgit push // uploading your own changes after a commit to the remote repo
