Function fake_tty::make_script_command

pub fn make_script_command(command: &str) -> String

Wraps the command in the script command that can execute it pretending to be a tty.

This can be executed in two ways:

• by passing it to bash -c <command> (you can use the bash_command function for this) or
• by running bash and piping the command to stdin, followed with the command exit

Examples

Pass it to bash -c <command>:

use std::process::{Command, Stdio};
use fake_tty::make_script_command;

let script_command = make_script_command("ls");

let output = Command::new("bash")
    .args(&["-c", &script_command])
    .stdout(Stdio::piped())
    .stderr(Stdio::piped())
    .output().unwrap();

assert!(output.status.success());

Pipe it to bash:

use std::process::{Command, Stdio};
use std::io::Write;
use fake_tty::make_script_command;

let mut script_command = make_script_command("ls");
script_command.push_str("\nexit");

let process = Command::new("bash")
    .stdin(Stdio::piped())
    .stdout(Stdio::piped())
    .stderr(Stdio::piped())
    .spawn()
    .unwrap();

let mut stdin = process.stdin.as_ref().unwrap();
stdin.write_all(script_command.as_bytes()).unwrap();
let output = process.wait_with_output().unwrap();

assert!(output.status.success());
