how to remove untracked files in Git?

I'm working on a branch, say "experimental" branch which I branch out from my master branch.Then, I generate a user model in experimental branch, but does not add them to index yet.

What do I have to do if I want to discard all the changes of the files recently added in my experimental branch? The untracked files are listed as below:

$ git status
 On branch new_chick
 Untracked files:
   (use "git add <file>..." to include in what will be committed)

       .project
       app/models/user.rb
       db/migrate/
       test/fixtures/users.yml
       test/unit/user_test.rb

I tried to run "git reset --hard" in hope to undo all those changes, but all the files above still show.

Anyone please shed some light on me?


To remove untracked files / directories do:

git clean -fdx

-f - force

-d - directories too

-x - remove ignored files too ( don't use this if you don't want to remove ignored files)


Use with Caution!
These commands can permanently delete arbitrary files, that you havn't thought of at first. Please double check and read all the comments below this answer and the --help section, etc., so to know all details to fine-tune your commands and surely get the expected result.


User interactive approach:

git clean -i -fd

Remove .classpath [y/N]? N
Remove .gitignore [y/N]? N
Remove .project [y/N]? N
Remove .settings/ [y/N]? N
Remove src/com/amazon/arsdumpgenerator/inspector/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/s3/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/s3/ [y/N]? y

-i for interactive
-f for force
-d for directory
-x for ignored files(add if required)

Note: Add -n or --dry-run to just check what it will do.


Those are untracked files. This means git isn't tracking them. It's only listing them because they're not in the git ignore file. Since they're not being tracked by git, git reset won't touch them.

If you want to blow away all untracked files, the simplest way is git clean -f (use git clean -n instead if you want to see what it would destroy without actually deleting anything). Otherwise, you can just delete the files you don't want by hand.
