Week 2 Notes for DAT2330 - Ian Allen
Supplement to Text, outlining the material done in class and lab.

Remember - knowing how to find out the answer is more important than
memorizing the answer.  Learn to fish!  RTFM![*]

Read the course announcements frequently, especially before tests.

Notes on FTP command syntax
===========================

The syntax of FTP commands is not the same as the syntax of Unix
commands.  This FTP command doesn't do what you think it does:

    ftp> ls -l filename
    output to local-file: filename?

If you answer "yes" to this prompt, you will copy the output of "ls -l"
into the file "filename" in your current directory, erasing what was
there before.  This is probably not what you want.

The FTP command names resemble Unix command names; but, they are *not*
Unix commands.  The syntax is different.  Be careful.

(Also, don't type FTP commands into Unix and expect that they will
work, e.g. "put filename".)

==========================
Unscrambling your Terminal
==========================

How to unscramble a terminal emulator that is in graphics characters set
mode, where see many special and line-drawing characters instead of your
typed text. 

(This might happen after you accidentally use "cat" to send a non-text
file to your terminal screen, e.g. "cat /bin/ls".)

To Fix (you may not be able to read what you are typing!):

  - On a Linux system (including Floppix) type:  setterm -reset

  - On ACADAIX type:  reset

  - On either type:   echo ^V^O     (that's CTRL-V CTRL-O)

The above should switch your terminal emulator back to its normal
character set.

Practice this now, in case it happens to you on a test!

=======================
Getting Out of Programs
=======================

Getting out of Unix programs; or, getting help: Try various things such as:

    help
    ?
    quit
    Q
    exit
    x
    ^D   (CTRL-D)
    ^C   (CTRL-C)
    :q!  (used in VI to exit without saving)
    logout
    bye
    ESC  (the ESC key)
    .    (a period)
    ^\   (CTRL-backslash)

One of the above usually works.  Sometimes you can use ^Z (CTRL-Z) to
"stop" the process temporarily, and then type "kill %%" to kill it.
(Remember to kill it, or it will sit there forever.)
