New To Unix

My Top 3

Secondly,is there any way of retrieving file permissions apart from in a LAYMAN readable form. "ls -l" retrieves file permissions in the form od -rw-rw—x 12 owner.name group …….

say i want the information in a table like style.

Owener read write —-
group read write —
other —- —- exec

I can do it using echo and create a table using tabs and all…
and so on….

Thirdly, I am using SSH prtocol to access a unix server to practice all commands. Is it possible that some commands dont run in the same way as they would on an actual unix machine.
