command-run

Rust library for running a command in a subprocess.

This library is a thin wrapper around the std::Command
type with a few additional convenient features:

• Print or log the command before running it
• Optionally return an error if the command is not successful
• Optionally combine stdout and stderr
• Optionally print the command’s output if the command fails
• The command can be formatted as a command-line string
• The Command type can be cloned and its fields are public

Dependencies and features

• log - this is an optional dependency. It can be disabled by
  turning off the logging feature:

  command-run = { version = "*", default-features = false }

• os_pipe - this dependency is used to implement combine_output.

Example

// This will return an error if the command did not exit successfully
// (controlled with the `check` field).
let output = Command::with_args("echo", &["hello", "world"])
    .enable_capture()
    .run()?;
assert_eq!(output.stdout_string_lossy(), "hello world\n");
