perms

Convert Unix style permissions to strings like ls (0755 => 'rwxr-xr-x')

Usage

Node.js

var Perms = require('perms');

Web

<script src="perms.min.js"></script>

Examples

Convert a mode to a human-readable string like ls(1) generates

var p = Perms.toString(0755);
console.log(p);

yields

rwxr-xr-x

Also handles special permissions

var p = Perms.toString(6660);
console.log(p);

yields

rwSrwS---

Go backwards as well!

var mode = Perms.toMode('rwxr-xr-t');
console.log(mode);

yields

1755

NOTE: This module makes it super tempting to parse ls(1)... don't do that!
