 The `#!` preprocessor directive enables unix shells to directly execute a C# file using `dotnet run`. For example:
 
 ```csharp
-#!/usr/local/share/dotnet/dotnet run
+#!/usr/bin/env dotnet run
 Console.WriteLine("Hello");
 ```
 
-The preceding code snippet informs a Unix shell to execute the file using `/usr/local/share/dotnet/dotnet run`. (Your installation directory for the `dotnet` CLI can be different on different Unix or macOS distributions). The `#!` line must be the first line in the file, and the following tokens are the program to run. You need to enable the *execute* (`x`) permission on the C# file for that feature.
+The preceding code snippet informs a Unix shell to execute the file using `dotnet run`. The `/usr/bin/env` command locates the `dotnet` executable in your PATH, making this approach portable across different Unix and macOS distributions.
