Chmod Calculator

Tick read, write and execute for owner, group and others to get the octal mode, the symbolic mode and an ls -l string.

How it works

  • Tick the boxes or type an octal value such as 755 — the boxes and the symbolic string stay in sync.
  • Special bits (setuid 4, setgid 2, sticky 1) are supported, giving modes like 4755.
  • A ready-to-run chmod command and an ls -l style string are shown so you can copy exactly what you need.
