What is this tool?
Unix file permissions control who can read, write, or execute a file, split into three owner/group/public triads each summing to one octal digit (read=4, write=2, execute=1). This calculator lets you toggle those bits to get the numeric (755) and symbolic (-rwxr-xr-x) modes, or paste an existing mode to see it broken down. Setuid, setgid, and sticky bits aren't covered.
How to use it
- Toggle read, write, and execute for owner, group, and public.
- Read the numeric and symbolic modes as they update live.
- Or paste an existing numeric or symbolic mode to load it into the grid.
