Module std::process 1.0.0
[−]
[src]
A module for working with processes.
Examples
Basic usage where we try to execute the cat
shell command:
use std::process::Command; let mut child = Command::new("/bin/cat") .arg("file.txt") .spawn() .expect("failed to execute child"); let ecode = child.wait() .expect("failed to wait on child"); assert!(ecode.success());Run
Calling a command with input and reading its output:
use std::process::{Command, Stdio}; use std::io::Write; let mut child = Command::new("/bin/cat") .stdin(Stdio::piped()) .stdout(Stdio::piped()) .spawn() .expect("failed to execute child"); { // limited borrow of stdin let stdin = child.stdin.as_mut().expect("failed to get stdin"); stdin.write_all(b"test").expect("failed to write to stdin"); } let output = child .wait_with_output() .expect("failed to wait on child"); assert_eq!(b"test", output.stdout.as_slice());Run
