he didn't know because that is incorrect. from perldoc -f -X:
-s File has nonzero size (returns size in bytes).
Now, now. Don't be giving away hints for his assignment...
However, I don't believe I've ever said anything wrong. To wit: OP
asked to emulate the UNIX shell command _ls -s_ which he seems to think
returns file size in bytes. It does not. To emulate ls -s one would
be expected to return the file size in blocks -- unless, of course, his
prof made (gasp!) an error.
