# 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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
