Function cmd

pub fn cmd<T, U>(program: T, args: U) -> Expression
where
    T: IntoExecutablePath,
    U: IntoIterator,
    U::Item: Into<OsString>,

Create a command given a program name and a collection of arguments. See also the cmd! macro, which doesn’t require a collection.

Example

use duct::cmd;

let args = vec!["foo", "bar", "baz"];

let output = cmd("echo", &args).read();

assert_eq!("foo bar baz", output.unwrap());
