Question

For moving two level up in the file hierarchy system using cd command once, we separates ( . . ) by which symbol?

(a) ?

(b) $

(c) *

(d) /

This question was posed to me in an internship interview.

This intriguing question originated from Absolute and Relative Pathnames topic in section The File System of Unix

Answer 1

Correct option is (d) /

To explain I would say: For changing your directory to the parent of current directory we can use ( . . ) with cd command. If we want to move more than one level up then we can use the ( . . ) separated by / .
