---

This creates provides a run function that does inline parsing of literal command line strings (handling escape codes and splitting at whitespace) and checks the ExitStatus of the command. If it didn’t succeed they will return a Err(...) instead of a Ok(...).

Note that the provided functions do return their own Output struct instead of std::process::Output.

Example

// stdout
let output = easy_process::run(r#"sh -c 'echo "1 2 3 4"'"#)?;
assert_eq!(&output.stdout, "1 2 3 4\n");

// stderr
let output = easy_process::run(r#"sh -c 'echo "1 2 3 4" >&2'"#)?;
assert_eq!(&output.stderr, "1 2 3 4\n");

Commands on windows are also supported in the same way:

let output = easy_process::run(r#"powershell /C 'echo "1 2 3 4"'"#)?;
assert_eq!(&output.stdout, "1 2 3 4\r\n");
