+# Download A File With Curl
+
+Though I typically think of cURL as a way of hitting an API endpoint to check
+its headers or see what it returns, it can also be used as an alternative to
+`wget` to download a file.
+
+With the `-O` option (short for `--remote-name`) we instruct cURL to save the
+contents of the remote file to a local file in the current directory _using the
+same name as the remote_.
+
+Here is an example:
+
+```bash
+$ curl -O https://www.apache.org/dist/db/derby/db-derby-10.17.1.0/db-derby-10.17.1.0-bin.zip.asc
+```
+
+This creates a file in my current directory called
+`db-derby-10.17.1.0-bin.zip.asc`. Notice it only uses the last part of the path
+for the file name.
+
+See `man curl` for more details.
