使用方法
Click the permission checkboxes to set the desired permissions for owner, group and others. The calculator shows the numeric (like 755) and symbolic (like rwxr-xr-x) representations in real time.
主な特徴
Permissions are grouped into three classes: owner, group and others. Each class can have read (r, value 4), write (w, value 2) and execute (x, value 1) permissions. These values are added together to get the number for each class.
Common permission modes
- 755 (rwxr-xr-x) - Directories and executable files
- 644 (rw-r--r--) - Regular files
- 700 (rwx------) - Private directories
- 600 (rw-------) - Sensitive files
- 777 (rwxrwxrwx) - Full permissions (use with caution)
