Chmod calculator

Convert Unix permissions between checkboxes, octal like 755 and rwxr-xr-x, with the chmod command.

What it does

Steps

1. Under Who, tick Read, Write and Execute for the owner, the group and others.
2. Read the permission in Octal (such as 755) and Symbolic (such as rwxr-xr-x) forms.
3. Or type an octal number or a symbolic string and see the boxes update.
4. Press Copy to take the full chmod command.
