17, -rwxrw-r--
The first character represents the file, directory (-) (d), link(l)
The other characters in a group of three (RWX), read (R), write (W), executive(x)
The first group of RWX: file owner permissions are read and write and execute
Second group rw-: with the same set of users and permissions on a file is read and write, but not executed
Third groups of r--: not with other users of the same group and file permissions are read but not write and execute
The available digital expression: r=4, w=2, x=1, and rwx=4+2+1=7
