사용 방법
- Enter a three or four digit chmod value such as 755, or a symbolic value such as rwxr-xr--.
- Review the owner, group, and others permission breakdown.
- Copy the numeric value, symbolic mode, or ready-to-run chmod command.
Read every permission group
The calculator shows separate read, write, and execute permissions for the owner, group, and others. The three octal digits map to those groups in that order.
Special bits are supported
Use a four digit value for setuid, setgid, and sticky bits, such as 1755. Symbolic input can use s and t in the executable positions, including rwxr-sr-t.
Private browser calculation
Parsing and formatting happen locally in your browser. No permission value is uploaded or stored by this page.

What does chmod 755 mean?
The owner has read, write, and execute permissions; group and others have read and execute permissions.
Can I enter symbolic permissions?
Yes. Enter a nine character value such as rw-r--r--, or include special bits in the executable positions.
What is the leading fourth digit?
It represents special bits: 4 for setuid, 2 for setgid, and 1 for the sticky bit. Values can be combined.
Does this change a file?
No. It only calculates and formats permissions. Copy the generated command and run it yourself when ready.
