+# Remove Untracked Files From A Directory
+
+Let's say I have a directory (`spec/cassettes`) full of a ton of generated YAML
+files. Most of these files are tracked by git. However, I just generated a
+bunch of new ones that are untracked. For whatever reason, I don't want these
+files. I need to delete them.
+
+Running `rm` on each of them is going to be too tedious. And it is tricky to
+target them for a bulk delete since there are a ton of other files in that
+directory that I want to keep.
+
+One way to approach this is have `git ls-files` help out with listing all files in the
+directory that are untracked. The `--others` flag filters to untracked files.
+
+```bash
+git ls-files --others --exclude-standard spec/cassettes
+```
+
+From there, I can pipe it to `rm` (with `xargs` collapsing all the files into a
+single line):
+
+```bash
+git ls-files --others --exclude-standard spec/cassettes | xargs rm
+```
+
+See `man git-ls-files` for more details.
