Showing and cleaning ignored files


Ignoring files is useful for filtering noise from the output of git status. But sometimes, it's necessary to check which files are ignored. This example will show you how to do that.

Getting ready

We'll continue in the repository from the last example.

How to do it...

To show the files we have ignored, we can use the clean command. Normally, the clean command will remove the untracked files from the working directory, but it is possible to run this in dry-run mode, -n, which just shows what would happen:

$ git clean -Xnd
Would remove bin/foobar
Would remove test.test
Would remove test.txt.bak

The options used in the preceding command specify the following:

  • -n, --dry-run: Only lists what will be removed
  • -X: Removes only the files ignored by Git
  • -d: Removes the untracked directories in addition to the untracked files

 

 

The ignored files can also be listed with the ls-files command:

$ git ls-files -o -i --exclude-standard
bin/foobar
test.test
test.txt.bak
