How Unix Permissions Work
Read (r = 4): View file contents or list directory entries.
Write (w = 2): Modify file contents or add/delete files in a directory.
Execute (x = 1): Run as a program or access files within a directory.
Each permission group (Owner, Group, Other) gets a digit 0-7, calculated by adding the bit values of enabled permissions. For example: rwx = 4+2+1 = 7, r-x = 4+1 = 5.

About Unix Permissions
What this tool does
Developer and design tools include CSS generators (gradients, shadows, glassmorphism), code playgrounds, color pickers, responsive previews, and reference charts for HTML tags, HTTP methods, and keyboard shortcuts.
Why use this tool
Front-end development involves constant context switching between code and visual output. Having generators and references in a single browser tab speeds up prototyping and reduces the need to search through documentation sites.
How it works
Each tool provides an interactive UI: you tweak parameters (colors, radii, durations), and the tool generates the corresponding CSS, HTML, or SVG code in real time. Copy the snippet directly into your project.
Pro tip
Use the CSS variable output option when available. It makes your generated code theme-friendly and easier to maintain across a design system.
