memorizing the answer.  Learn to fish!  RTFM!  (Read The Fine Manual)

In Week 6 (week06notes.txt) you learned about file and directory
permissions and the Unix file system (inodes and hard links).  You know
how to use the tar command.  You can read and post to Usenet news groups.
You can fetch a file using anonymous ftp.  You got an account on the
Course Linux Server and moved all your files there from ACADUNIX using
tar and scp.  You received Exercise #6 and submitted it by the due date.

You now know some basic meaning and usage of these Unix/Linux commands:

   bash passwd pwd cd mkdir rmdir rm ls
   vim cat more less man echo cp stty
   du wc date chmod who
   mesg mv head tail touch sort grep file diff
   sleep which whereis
   ^Z fg bg kill
   ln tar
   ssh scp ftp

Review questions:

    - Does the command name used on a command line affect the number
      of arguments passed by the shell?
    Answer: NO

    - Does the presence of redirection on a command line affect the
      number of arguments passed by the shell?
    Answer: NO
