How can I get rid of all the changes in all the files of my repository?
Say I am in a branch and I did some changes. git status returns a set of files in the "Changes not staged for commit" and I notice I would like to get rid of all of these changes in all the files. How can I do this with a single command?
I know I can do the following to checkout just one file:
git checkout -- <file>
I noticed that git checkout -- alone returns the list of all uncommited files. However, I cannot find a way to checkout all of them, something like git checkout --all.
I checked man git checkout and could not find anything. Also I saw Git: Checkout all files except one and tried git checkout . and did not work either.
Would I have to do it programmatically, by looping through the git checkout -- output?
回答1:
If you are at the root of your working directory, you can do git checkout -- . to check-out all files in the current HEAD and replace your local files.
You can also do git reset --hard to reset your working directory and replace all changes (including the index).

Other way which I found useful is:
git checkout <wildcard>
Example:
git checkout *.html
More generally:
git checkout <branch> <filename/wildcard>
