Chmod Umask Calculator

Chmod Umask Calculator is a desktop Linux developer utility for calculating
POSIX file and directory permission modes, default umask creation masks,
and ready-to-run shell commands.

Key Features:
- Interactive rwx Matrix & Umask Simulator: Synchronizes Owner, Group, and Other
Read, Write, and Execute checkboxes plus optional special flag bits (4/2/1
octal prefix) with live 4-digit octal (0755/0644), symbolic (-rwxr-xr-x),
and umask mask (0022/0002/0077) calculations showing effective Directory vs
File creation modes.
- Folder File Mode Inspector: Read-only browser inspecting real mode bits
(os.stat and stat.filemode) of files and folders inside your home directory
and comparing them against recommended standard modes.
- Command Snippet & Table Exporter: Generates ready-to-use chmod and
find -type f -perm command snippets and exports the mode reference matrix
and folder inspection table to CSV, Markdown, and JSON.
