What's the Correct Shebang Line for Running Go Programs Directly from the Command Line?

Utilizing Shebang Lines in Go Scripts

In the realm of scripting, shebang lines serve as executable interpreters. They allow shell scripts to specify how a script should be executed. For instance, Perl scripts commonly utilize the shebang line:

#!/usr/bin/env perl
Copy after login

This prompts the shell to interpret the script using the perl executable. So, what's the appropriate shebang line for Go programs?

To execute a Go program directly from the command line, the following shebang line should be employed:

//usr/bin/go run <pre class="brush:php;toolbar:false">//usr/bin/go run <pre class="brush:php;toolbar:false">//$GOROOT/bin/go run  $@ ; exit
Copy after login
$@ ; exit package main import "fmt" func main() { fmt.Println("Hello World!") } $@ ; exit

Here's an illustrative example:

Go interprets single-line comments starting with //, while the shell ignores characters after /. However, it's worth noting that the location of Go installations may vary. To account for this variation, the updated syntax below becomes:

This more flexible syntax effectively handles the different Go installation locations, ensuring seamless command-line execution of your Go scripts.
