Logging In
To log into cutthroat or the other Linux or Unix machines, simply enter the project username and password at the prompts. You can also reach these computers (like fcrao) via a secure shell, or ssh (we no longer like using telnet) by typing, for example:

ssh fcrao

Moving around
Once you've logged in, you will be in an xterm window. It is small and ugly. Open a some nicer ones by typing

xterm &

a couple of times.

Some other useful commands:

ls	list all files
cd	change directory
pwd	show current directory
rm	remove a file
cp	copy a file
more	display file contents
mv	move or rename a file
emacs	edit a file
grep string file	find string in file

Editing files
The easiest editor to use for updating README files or anything else is emacs. Type

emacs filename

and edit the file with the arrow keys, backspace, whatever. Emacs has a number of control and escape sequences which make it both extremely powerful and extremely difficult to master! Some simple and useful ones are:

Ctrl-d	Delete forward character
Esc-d	Delete forward word
Ctrl-f/b	Move forward/back a character
Esc-f/b	Move forward/back a word (get the trend with Ctrl and Esc?)
Ctrl-a/e	Move to beginning/end of line
Ctrl-x Ctrl-c	Save and exit (reply "yes" to save)

Mail, netscape, etc.
Read the mail, if there is any, every time you log onto fcrao. There may be important messages from UMIGS members or other observers. Simply type "mail" at the prompt. The following commands are useful:

?	List all commands
f	Show current message header
h	Show all message headers
number	Read message number number
d [number/number-number]	Delete current message [message number/range]
m username@host	Send mail to username@host
r	Reply to message
q	Update and quit mail
x	Quit mail without updating

Send mail at the prompt (outside mail) by typing

mail username@host

To finish a mail message and send it, type "." by itself on a line and return.
