chmod Calculator
Convert between octal, symbolic and checkbox file permissions.
How it works
Toggle read, write, and execute for owner, group, and others to see octal (644) and symbolic (rw-r--r--) permissions update live. Copy the chmod command when done.
Example: 644 means rw-r--r-- — owner can read/write, everyone else read-only.
rwxr-xr-xRead
