Question

If a file is read protected, we can write to the file.

(a) True

(b) False

The question was asked in an online quiz.

This is a very interesting question from File Ownership and Permissions topic in section Basic File Attributes of Unix

Answer 1

Right answer is (b) False

The best explanation: If a file is not readable then it is obvious that we cannot write anything to the file. To write anything to a file it should be readable first. But if a file is writable then we can read the file easily but the reverse is not true.
