RUST Execute command

In RUST, There are multiple ways to spawn a child process and execute an arbitrary command on the machine:

  • spawn — runs the program and returns a value with details
  • output — runs the program and returns the output
  • status — runs the program and returns the exit code

Below is an example from docs for Executing a command

:

use std::process::Command;

Command::new("ls")
        .arg("-l")
        .arg("-a")
        .spawn()
        .expect("ls command failed to start");

Another Example of Executing RUST Command

use std::process::Command;
let output = Command::new("/bin/cat")
                     .arg("file.txt")
                     .output()
                     .expect("failed to execute process");

println!("status: {}", output.status);
println!("stdout: {}", String::from_utf8_lossy(&output.stdout));
println!("stderr: {}", String::from_utf8_lossy(&output.stderr));

assert!(output.status.success());
