Handy Orchard

Unix permission calculator

Convert three-digit Unix permissions to readable owner, group and other permissions without changing files.

Your input

Use 755 or rwxr-xr-x; replace individual r/w/x positions with - to remove permissions.

Outputs are cleared when the input changes.

Result

Enter your data or use the example, then run the tool.

Worked example

755 becomes rwxr-xr-x; 644 becomes rw-r--r--.

Method

Each group adds read 4, write 2 and execute 1, giving an octal digit and corresponding symbolic group.

Limits

No ACL, setuid, setgid, sticky bits or execution. This does not recommend a universally safe setting.
