+# Find All Files With A Specific Extension With fd
+
+The best way with [`fd`](https://github.com/sharkdp/fd) to match on files with
+a specific extension is to use the `-e` flag.
+
+Here is how you'd find all `.ts` files:
+
+```bash
+$ fd -e ts
+```
+
+You can use the flag multiple times to specify multiple file extensions. This
+will turn up all TypeScript and JavaScript files:
+
+```bash
+$ fd -e ts -e js
+```
+
+Alternatively, you can use regex in the filename pattern to match on several
+file extensions like so:
+
+```bash
+$ fd '.*\.(js|ts|jsx|tsx)$'
+```
