Isbin

Tiny little helper library to determine if a certain binary is available within $PATH or any additional folder.

Installation

$ npm install isbin

Usage

var isbin = require('isbin');

// Test against $PATH
isbin('mysql', function(exists) {
  console.log(exists); // ==> Boolean
});

// With additional path to test
isbin('mysql', '/usr/local/bin', function(exists) {
  console.log(exists); // ==> Boolean
});

// Or multiple ones
isbin('mysql', ['/usr/local/bin', '/home/me/bins'], function(exists) {
  console.log(exists); // ==> Boolean
});

There are also synchronous versions available

var exists = isbin('mysql');
var exists = isbin('mysql', '/usr/local/bin');
var exists = isbin('mysql', ['/usr/local/bin', '/home/me/bins']);

Running the tests

$ npm install
$ make test
