	INTRODUCTION TO E-MAIL IN BIOMED COMPUTER (UNIX with vi editor)

			     NETSIVI BEN-AMOTS



Mail via computer is used widely for sending letters in the Technion and

between countries.  An outstanding application is writing a paper with

co-author in other countries.  You mail him your last version of the paper via

the computer e-mail.  He makes his corrections and modifications and mails it

to your computer.  These iterations are VERY fast.  More than FAX - you do not

print at all.  You need only to know how to use few commands of the mail.

Here is a presentation of the necessary commands in BIOMED computer, (that

works with UNIX.) Remember that all UNIX computers are VERY case-sensitive.



***************************************************************************

**REMEMBER NOT TO PRESS CTRL-Z!!!  Leave mail with QUIT or EXIT commands.**

***************************************************************************



biomed-~} mail	   You write: mail (This is alias to the unix command mush -f)

The computer answers

>  1	Moshe Kohen	   Dec	 3   subject of letter

That shows you that you have a letter number 1 from Moshe Kohen, and more

lines for each letter.	Then you have the prompt

yourname [1/3] MAIL>

that means you have 3 letters, and the pointer is on letter no. 1.



			 HOW TO DEAL WITH COMING MAIL

You may write:

yourname [1/3] MAIL> dir       (This is alias to the original command headers)

and get the list of letters again.

To read one of the letters you write its number and press the RETURN key.

yourname [1/3] MAIL> 1

After reading it, you may delete it:

yourname [1/3] MAIL> delete 1

yourname [1/3] MAIL> dir

or copy it:

yourname [1/3] MAIL> 1

yourname [1/3] MAIL> save filename

It will save the file that was read with the previous command, in directory

Mail_Folders, from where you move it (after leaving mail) with UNIX command mv.

To leave mail, you write

yourname [1/3] MAIL> quit

and get the prompt

biomed-~}

If BEFORE leaving, you regret that you deleted a letter of your mail, write

yourname [1/3] MAIL> exit

instead quit, and the deleted letters will revive again.

After leaving mail, you may move saved mail.  For example:

biomed-~}mv /u/yourloginname/Mail_Folders/filename /u/yourloginname/.



			HOW TO SEND MAIL (A LETTER)



Your address is yourloginname@biomed.technion.ac.il

Replace yourloginname with the word you login with, (probably your name.)



To send mail, you write: mail

yourname [1/3] MAIL> mail

and get:

TO:

If you send mail in the Technion, just write:

TO: hisloginname@hiscomputername

For example:

TO: moshe@biomed

If you send mail outside the Technion, type his full address:

TO: hisloginname@hiscomputername.something.something.hiscountrycode

Replace correctly, or type the exact e-mail address you have seen in his

letter, and then press RETURN key.  Now you have prompt:  Subject:

and you write the subject of the letter.  Example:

Subject: Establish connection

				vi EDITOR



Now the computer enters you automatically into the vi editor, which is VERY

UNfriendly.  Also needs special KERMIT install for PC-terminals (not for

tektronix).  If you write your message on the spot, press the key i.  Now

write your message, WITHOUT USING THE ARROWS, yet you may use the BS BACKSPACE

key.  When completed, or for corrections, press CTRL-3 (press CTRL key, and

BEFORE removing your finger from the CTRL key, press with a finger of the

other hand the 3 key.) In PC-terminals, use ESC instead CTRL-3 (after special

KERMIT installation; ask me - Netsivi).	You should hear a beep.  If not, press

CTRL-3 again.  Now you heard the beep.	If you want to correct, locate the

right place with the arrows.  Remember to use the arrows only after you heard

the beep.



To enter text, press the i key once, and then write the text.  Then - CTRL-3

until you hear the beep.  To delete a character, locate it, then press the x

key once.  To add a line below the current line, press the key o once.  To

delete the current line, locate it, then press the key d TWICE.  Long text:

CTRL-f means roll page Forward; CTRL-u means roll page backward.



When your letter is completed, press CTRL-3 and hear the beep, then press :

that is press SHIFT, and BEFORE removing your finger, press with a finger of

the other hand the :  key.  You are now at the bottom of the screen.  Now

write wq, and press the RETURN key.



The computer suggests you to press ^D.	It means press CTRL-d.	You press the

CTRL key, and BEFORE removing your finger, press with a finger of the other

hand the d key.  If you have a prompt:

Cc:

Press RETURN, or, if you want a copy of your letter to yourself, enter your

address:

yourloginname@biomed

The computer ask you to press s, c, or d.  Now press s, and the

letter is already on its way.  You have again the prompt:

yourname [1/3] MAIL>

Write dir to see your copy of the letter, or if the letter came back because

of incorrect address.

yourname [1/3] MAIL> dir

			  MAILING A PAPER OR A COMPUTER PROGRAM



You may want to send a letter that you have written previously with your

favorite editor (ASCII, please), or it can be your new computer program written

for FORTRAN or C compilers, or your paper in an ASCII file.  NOT THE BINARIES,

PLEASE!!!  To do it:



Repeat the above procedure, but when you enter vi, DO NOT PRESS THE i KEY.

Press : (SHIFT with : together.)  You are at the bottom of the screen.	Now

write:

r /u/yourloginname/yourfilename      and press the RETURN key.

Remember, small r.

Remember to replace to your real login name and file name.

Remember to give the full path to your file. VERY EASY TO FORGET! DON'T FORGET!

Done correctly, you see the first page on the screen.  Otherwise, it says it

cannot find the file.

Now, CTRL-3 (beep), SHIFT :, wq RETURN, CTRL-d, s, just like above.



		FRIENDLY EDITOR pico (instead vi editor)



You may ask Netsivi to make your e-mail work with the new friendly editor pico,

instead awful vi editor.  Your work with pico is natural.

OPERATION outside mail: pico namefile	  (small letters, please)

Mail automatically invokes pico editor (instead vi), once Netsivi makes the

necessary changes.

LEAVING EDITOR: CTRL-X	  (IT ASKS TO SAVE OR NOT)

Save without leaving editor: CTRL-O

Bring file: CTRL-R     and then /u/yourloginname/path/yourfilename

Remember to give the full path to your file. VERY EASY TO FORGET! DON'T FORGET!

Check spelling: CTRL-T

Delete line: CTRL-K

Undelete last deleted line at cursor position: CTRL-U

Next page: CTRL-V

Previous page: CTRL-Y

Look in two lines at screen bottom for help.

More detailed help: CTRL-G

After leaving pico with CTRL-X, follow the above instructions for mail.



That ends the minimum necessary to deal with e-mail.  The mail has more

possibilities and facilities to make mailing easier, and in the future you

will learn them.
