command-run

Rust library for running a command in a subprocess.

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

• Print and/or log the command before running it
• Optionally return an error if the command is not successful
• The command can be formatted as a command-line string
• The [Command] type can be cloned and its fields are public

Dependencies and features

Other than the standard library, this crate has only one dependency: the [log] crate. That dependency can be disabled:

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

Example

rust // 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"); // End readme example
