cargo-new-script is a cargo command to quickly generate a cargo-script.

As of February 2024, cargo-script is available on nightly. See the tracking issues for cargo and rustc.

cargo install --git https://github.com/avsaase/cargo-new-script

Currently, only unix operating systems are supported.

cargo new-script my-script

This generates a file called my-script.rs in your current working directory:

#!/usr/bin/env -S cargo +nightly -Zscript
---
[dependencies]

---

fn main() {
    println!("Hello, world!");
}

Run your script with ./my-script.rs. The generated script is already made executable.

See cargo new-script --help for limited options.
