+# List Untracked Files For Scripting
+
+You'll generally run `git status` to get an overview of the index and working
+tree of a git project. This is a _porcelain_ command meant for a Git end-user.
+If you want to do some scripting, you'll want a _plumbing_ command like
+`ls_files`.
+
+The `git ls-files` command will
+
+> Show information about files in the index and the working tree
+
+This command can be used to list all untracked files in the working tree with
+two flags.
+
+1. The `--others` flag will show untracked files in the output
+2. The `--exclude-standard` will use the standard ignore files like
+   `.gitignore` and `.git/info/exclude`.
+
+Put it all together and you've got:
+
+```bash
+$ git ls-files --others --exclude-standard
+```
+
+In [Make One-Line Commands Interactive with
+fzf](https://www.youtube.com/watch?v=wf5eXdwfVws), I show how to use this with
+`fzf` to interactively remove untracked files that are no longer wanted.
