 This command is equivalent to `run`, but it changes the way Scala CLI parses options (used to configure the tool) and
 inputs (the sources of your project) in order to be compatible with `shebang` scripts.
+The command `shebang` also allows script files to be executed even if they have no file extension,
+provided they start with the [`shebang` header](../guides/shebang.md#shebang-script-headers).
 
 Normally, inputs and `scala-cli` options can be mixed. Program arguments (to be passed to your app) have to be specified
 after `--` (double dash) separator.

+### Script files' extensions
+
+When running the `shebang` subcommand, script files don't need the `.sc` extension,
+but they are then REQUIRED to start with a shebang line:
+
+```scala title=hello-with-shebang
+#!/usr/bin/env -S scala-cli shebang -S 3
+
+println(args.size)
+println(args.headOption)
