Problem
1. What do you understand by the listing of a file? How will you save the complete listing of all files and directories (including the hidden ones) in the system?
2. Show the octal representation of these permissions:
(i) rwxr-xrw-,
(ii) rw-r----- ,
(iii) --x-w-r--.
3. What will the permissions string look like for these octal values?
(i) 567,
(ii) 623,
(iii) 421.
