Hi Sir
I have implemented my solution. Should I send the patch in reply to
this mail or as a different mail? Also should I label it as v2? I have
also addressed the warnings out of list command output in it. for eg.

WARNING:REPEATED_WORD: Possible repeated word: 'root'
#18:
  drwxr-xr-x. 2 root root    0 Apr 17 10:53 .

WARNING:REPEATED_WORD: Possible repeated word: 'nobody'
#28:
drwxr-xr-x 5 nobody nobody    0 Jan 25 18:08 .

Sincerely
Aditya
