Tool Name
Chmod Calculator
Proposed Filename
chmod-calculator.html
Category
Developer Utilities
Description
A standalone browser-based utility that helps users calculate and understand Unix/Linux file permissions. Users can interactively toggle read, write, and execute permissions for the owner, group, and others to instantly generate the corresponding numeric (octal) and symbolic chmod representations. The tool is useful for developers, system administrators, DevOps engineers, and Linux learners working with file permissions. All calculations happen locally in the browser without requiring any backend services.
Key Features
Interactive permission matrix for Owner, Group, and Others.
Generate numeric (octal) chmod values (e.g., 755, 644, 777).
Display symbolic representation (e.g., rwxr-xr-x).
Support special permission bits:
SetUID
SetGID
Sticky Bit
Live updates as permissions are changed.
Explain the meaning of each permission combination.
One-click copy for numeric and symbolic values.
Reset to common presets (644, 755, 600, 777, etc.).
Fully responsive, keyboard accessible, and works entirely offline.
Suggested Difficulty
Easy
