exec-sh

Execute shell command forwarding all stdio streams.

Showcase

// JavaScript

execSh("echo hello exec-sh && bash", { cwd: "/home" }, function(err){
  if (err) {
    console.log("Exit code: ", err.code);
  }
});

// Terminal output: interactive bash session

hello exec-sh
bash-3.2$ pwd
/home
bash-3.2$ exit 99
exit
Exit code:  99

Features

exec-sh is a wrapper for child_process.spawn with improvements:

• Cross platform command execution:
  • Windows: cmd /C COMMAND
  • others: sh -c COMMAND
• Fowrards all stdio streams to current terminal (by default):
  • try execSh("bash")
  • try execsh("echo -n Say: && read i && echo Said:$i")
• stdout and stderr are passed to callback when available
  • try execSh("pwd", console.log)

Installation

npm install exec-sh

Usage

var execSh = require("../");

// run interactive bash shell
execSh("echo lorem && bash", { cwd: "/home" }, function(err){
  if (err) {
    console.log("Exit code: ", err.code);
    return;
  }

  // collect streams output
  var child = execSh(["bash -c id", "echo lorem >&2"], true,
    function(err, stdout, stderr){
      console.log("error: ", err);
      console.log("stdout: ", stdout);
      console.log("stderr: ", stderr);
    });
});
