Saving State

About to attempt something drastic? Before you do, take a snapshot of all files in the current directory and manage it with git.

$ git init
$ git add .
$ git commit -m "My git backup"

Now if something went bad, restore the pristine version.

$ git reset --hard

Add, Delete, Rename

If you add new files or subdirectories to your git project, you’ll have to tell Git.

$ git add readme.txt

Similarly, if you want Git to forget about certain files.

$ git rm readme.txt

Renaming a file is the same as removing the old name and adding the new name. There’s also the shortcut git mv.

$ git mv readme.txt readme.htm
