Permcon

Permission Converter - A simple utility module to convert file-system permission from symbolic to octal notation and vice versa. For example, rw-rw-r-- to 664 or 0743 to rwxr---wx. It also has a cli, incase you find it useful. The library is fully tested with 100% test coverage.

Example Usages:

const { isOctal, isSymbolic, analyze, convert } = require("permcon");

isOctal("764") // true
isOctal("0764") // true

isSymbolic("rwxrw-r--") // true
isSymbolic("lrwxrw-r--") // true
isSymbolic("rwSrw-r--") // true

convert("drwxr---wx") // 0743
convert("rwxr---wx") // 0743

// or the other way around
convert("743") // rwxr---wx

analyze("drwxr---wx")
/*
{
  fileType: 'Directory',
  symbolic: 'rwxr---wx',
  octal: '0743',
  owner: { read: true, write: true, execute: true },
  group: { read: true, write: false, execute: false },
  other: { read: false, write: true, execute: true }
  suid: false,
