000---------chmod 000 path/to/fileChmod Calculator
Compute Unix file permissions by clicking checkboxes or typing an octal value like 755 or 4755. The calculator shows the symbolic notation (such as rwxr-xr-x), the numeric result, and a ready-to-use chmod command.
You can toggle read, write, and execute for owner, group, and others, and include special bits when needed. All permission logic runs entirely in your browser.
