Why Choose Fixie?
chmodcommand.com serves as both a calculator and a chmod reference with individual pages explaining common permission patterns. Fixie takes a different approach by consolidating everything into a single interactive interface where you can toggle permissions visually and see the results update in real time.
The color-coded permission grid makes it immediately clear which permissions are enabled — blue for read, red for write, green for execute, and purple for special bits. As you click each cell, you see the octal code, symbolic notation, chmod command, and ls -la output all update instantly. This tight feedback loop helps you learn how chmod works while building your command.
Fixie includes dedicated support for special bits (setuid, setgid, sticky) with clear visual toggles and explanations. The ls -la preview shows you exactly how these special bits will appear in your terminal (lowercase s/t when execute is set, uppercase S/T when it's not). The file type selector lets you switch between regular files, directories, and symlinks to see the difference in the ls output. With 10 built-in presets covering common use cases from SSH keys (600) to shared directories (775) to /tmp (1777), you can quickly apply standard patterns without memorizing octal codes.
