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:

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

Example

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