Question

The permission -rwxr-r- represented in octal expression will be ________.

1) 777
2) 666
3) 744

Answer 1

The permission -rwxr-r- is represented by the octal number 744, which designates full permissions for the user, and read-only permissions for the group and others.

Step-by-step explanation:

The file permission -rwxr-r- when converted to octal representation, results in 744. This octal number corresponds to the permissions set for the user, group, and others in that order. The user (owner) has read (r), write (w), and execute (x) permissions represented by 7. The group has read (r) permission represented by 4, and others also have read (r) permission represented by another 4.
