About Chmod Calculator
This tool helps you calculate and understand Unix/Linux file permissions. You can set permissions for the owner, group, and others by checking the read (r), write (w), and execute (x) boxes. The calculator will show the corresponding octal (e.g., 755) and symbolic (e.g., rwxr-xr-x) notations.
The octal notation is a sum of values: read (4), write (2), and execute (1). For example, read + write (4+2=6), read + execute (4+1=5).
