+# Count All Files Of Specific Type Tracked By Git
+
+I want to get a count of all the markdown files in my [TIL
+repo](https://github.com/jbranchaud/til). Since all the files I care about are
+tracked by `git`, I can use `git ls-files` to get a listing of all files. That
+command on its own lists all files tracked by your git repository. Though there
+are many other flags we can apply, that will do for my purposes.
+
+By giving `git ls-files` a pattern to match against, I can turn up just, for
+instance, markdown files (`*.md`). I can pipe that to `wc -l` to get a count
+rather than exploding my terminal with a list of file names.
+
+```bash
+❯ git ls-files '*.md' | wc -l
+    1503
+```
+
+That command includes `README.md` and `CONTRIBUTING.md`, but really I only want
+to count the markdown files that constitute a TIL. Those all happen to be
+nested under a single directory. So I can tweak the glob pattern like so:
+
+```bash
+❯ git ls-files '*/*.md' | wc -l
+    1501
+```
+
+See `man git-ls-files` for more details.
