How would you represent r-xrw-r in octal notation?

Understand the Problem

The question is asking how to convert the file permission notation 'r-xrw-r' into octal notation. Each permission character corresponds to a specific value in octal, where 'r' (read) is 4, 'w' (write) is 2, and 'x' (execute) is 1. The absence of permission is represented as 0. We will evaluate each set of user, group, and others permissions to construct the octal representation.

More Information

The string 'r-xrw-r' breaks down into octal as: user (r-x = 4+0+1 = 5), group (rw- = 4+2+0 = 6), others (r = 4). Resulting in the octal value 654.

Tips

A common mistake is to sum the values incorrectly or misinterpret the order. Double-check your groupings and additions.
