lookpath

To check if the command exists and where the executable file is, WITHOUT using child_process.

npm install lookpath

Example usage

const { lookpath } = require('lookpath');

const p = await lookpath('bash');
// "/bin/bash", otherwise "undefined"

Advanced usage

const p = await lookpath('bash', {
  include: ['/home/hiromu/.bin'],
  exclude: ['/mnt']
});
// include: Do scan also under `~/.bin`
// exclude: Do NOT scan under `/mnt`

Motivation

I don't want to spawn child_process in order to kick which, where, whereis, or command -v.
then I checked Go implementation of exec.LookPath.
- src/os/exec/lp_unix.go - The Go Programming Language
so I concluded that scanning under $PATH or $Path is the best straightforward way to check if the command exists.
