Toggle the permission checkboxes for owner, group, and others. The numeric (octal) and symbolic representations update instantly. You can also enter a 3-digit octal number directly.
Unix Permissions
Unix file permissions control read (4), write (2), and execute (1) access for three groups: owner, group, and others. The octal representation is the sum of these values for each group. For example, 755 means rwx for owner, r-x for group and others.
