Node module to check if a command-line command exists.
Forked from command-exists.

Installation

For npm users

$ npm i command-exists-promise

For yarn users

$ yarn add command-exists-promise

The function returns a promise that will resolve to true if the command exists and false if it doesn't.
On UNIX, the promise will resolve to true if the command is a path to an executable file. On Windows, it will resolve to true for any existing file.
