Function duct_sh::sh [−] [src]

pub fn sh(command: &'static str) -> Expression

Create a command from a static string of shell code.

This invokes the operating system's shell to execute the string: /bin/sh on Unix-like systems and cmd.exe (or %COMSPEC%) on Windows. This can be very convenient sometimes, especially in small scripts and examples. You don't need to quote each argument, and all the operators like | and > work as usual.

sh avoids security issues by accepting only static strings. If you need to build shell commands at runtime, read the documentation for sh_dangerous.

Example

use duct_sh::sh;

let output = sh("echo foo bar baz").read();

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