How Do I Remove Local (Untracked) Files from the Current Git Working Tree?

In Git, untracked files are files that exist in your working directory but are not part of your repository's version control. Removing these files can help keep your working directory clean. Git provides commands to identify and remove untracked files.

Steps to Remove Local (Untracked) Files

1. List Untracked Files

Before removing untracked files, you might want to see which files are untracked. You can use the git status command to list them.

git status

This will output a list of untracked files under the "Untracked files:" section.

2. Remove Untracked Files Using git clean

Git has a built-in command called git clean that can be used to remove untracked files. Be cautious with this command, as it will delete files permanently.

Dry Run (Preview)

To preview which files will be removed without actually deleting them, use the -n or --dry-run option.

git clean -n

or

git clean --dry-run

This will list the untracked files and directories that would be removed.

Remove Untracked Files

To remove the untracked files, use the -f or --force option.

git clean -f

or

git clean --force

Remove Untracked Directories

By default, git clean does not remove untracked directories. To remove untracked directories as well, use the -d option along with -f.

git clean -fd

or

git clean --force --dir

Remove Ignored Files

If you also want to remove files that are ignored by Git (listed in .gitignore), use the -x option.

git clean -fx

or

git clean --force --ignored

Remove Only Ignored Files

To remove only the ignored files and not the untracked files, use the -X option.

git clean -fX

or

git clean --force --only-ignored

Summary of Commands

1. List Untracked Files:

   git status

2. Dry Run (Preview):

   git clean -n

3. Remove Untracked Files:

   git clean -f

4. Remove Untracked Files and Directories:

   git clean -fd

5. Remove Untracked and Ignored Files:

   git clean -fx

6. Remove Only Ignored Files:

   git clean -fX

Example Workflow

1. Preview Untracked Files to Be Removed:

   git clean -n

2. Remove Untracked Files:

   git clean -f

3. Remove Untracked Files and Directories:

   git clean -fd

Conclusion

Using git clean allows you to efficiently remove untracked files and directories from your working tree, helping you maintain a clean working environment. Always use the dry run option (-n) first to preview the files that will be removed, especially when working with critical projects.
