git-clean - Remove untracked files from the working tree

Synopsis

git clean [-d] [-f] [-i] [-n] [-q] [-e <pattern>] [-x | -X] [--] <path>…​

Description

Cleans the working tree by recursively removing files that are not under version control, starting from the current directory.

Normally, only files unknown to Git are removed, but if the -x option is specified, ignored files are also removed. This can, for example, be useful to remove all build products.

If any optional <path>... arguments are given, only those paths are affected.

Step 1 is to show what will be deleted by using the -n option:

# Print out the list of files and directories which will be removed (dry run)
git clean -n -d

Clean Step - beware: this will delete files:

# Delete the files from the repository
git clean -f

• To remove directories, run git clean -f -d or git clean -fd
• To remove ignored files, run git clean -f -X or git clean -fX
• To remove ignored and non-ignored files, run git clean -f -x or git clean -fx

Note the case difference on the X for the two latter commands.

If clean.requireForce is set to "true" (the default) in your configuration, one needs to specify -f otherwise nothing will actually happen.

Again see the git-clean docs for more information.

Options

-f, --force

If the Git configuration variable clean.requireForce is not set to false, git clean will refuse to run unless given -f, -n or -i.

-x

Don’t use the standard ignore rules read from .gitignore (per directory) and $GIT_DIR/info/exclude, but do still use the ignore rules given with -e options. This allows removing all untracked files, including build products. This can be used (possibly in conjunction with git reset) to create a pristine working directory to test a clean build.

-X

Remove only files ignored by Git. This may be useful to rebuild everything from scratch, but keep manually created files.

-n, --dry-run

Don’t actually remove anything, just show what would be done.

-d

Remove untracked directories in addition to untracked files. If an untracked directory is managed by a different Git repository, it is not removed by default. Use -f option twice if you really want to remove such a directory.

First, clone a remote Git repository and cd into it:

$ git clone git://example.com/myproject
$ cd myproject

Next, look at the local branches in your repository:

$ git branch
* master

But there are other branches hiding in your repository! You can see these using the -a flag:

$ git branch -a
* master
  remotes/origin/HEAD
  remotes/origin/master
  remotes/origin/v1.0-stable
  remotes/origin/experimental

If you just want to take a quick peek at an upstream branch, you can check it out directly:

$ git checkout origin/experimental

But if you want to work on that branch, you'll need to create a local tracking branch which is done automatically by:

$ git checkout experimental

and you will see

Branch experimental set up to track remote branch experimental from origin.
Switched to a new branch 'experimental'

Here, "new branch" simply means that the branch is taken from the index and created locally for you. As the previous line tells you, the branch is being set up to track the remote branch, which usually means the origin/branch_name branch.

Now, if you look at your local branches, this is what you'll see:

$ git branch
* experimental
  master

You can actually track more than one remote repository using git remote.

$ git remote add win32 git://example.com/users/joe/myproject-win32-port
$ git branch -a
* master
  remotes/origin/HEAD
  remotes/origin/master
  remotes/origin/v1.0-stable
  remotes/origin/experimental
  remotes/win32/master
  remotes/win32/new-widgets

At this point, things are getting pretty crazy, so run gitk to see what's going on:

$ gitk --all &
