How it works
Free chmod calculator. Check read, write, and execute for owner, group, and others, including setuid, setgid, and the sticky bit. See the octal mode, the symbolic mode, and the chmod command.
- 01
Check the boxes or type a mode
Each row is owner, group, or others. You can also paste 755 or rwxr-xr-x.
- 02
Read the octal and symbolic forms
They stay in sync. Special bits add a leading octal digit and replace x with s or t.
- 03
Copy the command
The chmod line uses the path you type, or file when the path is empty.
