It is easier to diagnose problems with a command when you include the exact 
command you ran. That said, the first thing to try doing is believing the 
error message you are getting: the target file you ask unzip to unzip is 
not a zip archive.

 From the output of the command, it *appears* you entered something like 
"unzip /usr/bin/unzip", since the "Archive:" part of the message should be 
reporting the name of the file you are trying to unzip. Of course, the 
executable unzip is not iself a zip file, so unzip cannot unzip itself.

As you can see here, I get this same sort of report when I try to unzip an 
ordinary text file (it matches word for word, except for the names of the 
files).

         autovcr@waverly:~$ unzip vcrlogfile.txt
         Archive:  vcrlogfile.txt
         End-of-central-directory signature not found.  Either this file is not
         a zipfile, or it constitutes one disk of a multi-part archive.  In the
         latter case the central directory and zipfile comment will be found on
         the last disk(s) of this archive.
         unzip:  cannot find zipfile directory in one of vcrlogfile.txt or
                         vcrlogfile.txt.zip, and cannot find 
vcrlogfile.txt.ZIP, period.

If I have guessed incorrectly here about what command you entered, please 
report the actual command you did enter to get this output.

I don't use the other commands you asked about, so I can't make any 
suggestions there.
