How does this tool work?
Calculates file permissions (chmod values) intuitively.
Select the read, write, and execute permissions for the owner, group, and public (others) by checking the respective boxes. The tool instantly generates the corresponding numeric value (e.g., 755) and symbolic value (e.g., rwxr-xr-x), which you can then copy to your clipboard for use in terminal commands.
