directories (for example: \stuff\text), Unix uses a / (for
example: /stuff/text). So to change from your present
directory to the stuff/text lan flash designer sub-directory, you would type
cd stuff/text
and then hit enter. As in MS-DOS, you do not need the first
backslash if the subdirectory comes off the directory you're
already in. To move back up a directory tree, you would type
cd ..
followed by enter. Note the space between the cd and the two
periods -- this is where MS-DOS users will really go nuts.
cp Copies a file. The syntax is
cp file1 file2
which would copy file1 to file2 (or overwrite file2 with
file1).
ls This command, when followed by enter, tells you what's in the
directory, similar to the DOS dir command, except in
alphabetical order.
lan flash designer ls | more
will stop the listing every 24 lines -- handy if there are a
lot of things in the directory. The basic ls command does not
list "hidden" files, such as the .login file that controls
how your system interacts with Unix. To see these files, type
ls -a or ls -a | more
ls -l will tell you the size of each file in bytes and tell
you when each was created or modified.
mv Similar to the MS-DOS rename command.
mv file1 file2
will rename file1 as file2, The command can
also be used to move files between directories.
mv file1 News
lan flash designer would move file1 to your News directory.
rm Deletes a file. Type
rm filename
and hit enter (but lan flash designer beware: when you hit enter, it's gone for
good).
WILDCARDS: When searching for, copying or deleting files, you can
use "wildcards" if you are not sure of the file's exact name.
ls man*
would find the following files:
manual, manual.txt, man-o-man.
Use a question mark when you're sure about all but one or two characters.
For example,
ls man?
would find a file called mane, but not one called manual.
2.7 WHEN THINGS GO WRONG
* You send a message but get back an ominous looking message from
MAILER-DAEMON containing up to several dozen lines of computerese
followed by your message.
Somewhere in those lines you can often find a clue to what went
wrong. You might have made a mistake in spelling the e-mail address.
The site to which you're sending mail might have been down for
maintenance or a problem. You may have used the wrong "translation" for
mail to a non-Internet network.
* You call up your host system's text editor to write a message or
reply to one and can't seem to get out.
If it's emacs, try control-X, control-C (in other words, hit your
control key and your X key at the same time, followed by control and C).
If worse comes to worse, you can hang up.
* In elm, you accidentally hit the D key for a message you want to
save.
Type the number of the message, hit enter and then U, which will
"un-delete" the message. This works flash designer stamford only before you exit Elm; once you
quit, the message is gone.
* You try to upload an ASCII message you've written on your own
computer into a message you're preparing in Elm or Pine and you get a
lot of left brackets, capital Ms, Ks and Ls and some funny-looking
characters.
Believe it or not, your message will actually wind up looking fine;
all that garbage is temporary and reflects the problems some Unix text
processors have with ASCII lan flash designer uploads. But it will take much longer for
your upload to finish.
One way to deal with this is to call up the
simple mail program, which will not produce any weird characters when you
upload a text file into a message.
Another way (which is better if your
prepared message is a response to somebody's mail), is to create a text
file on your host system with cat, for example,
cat>file
and then upload your text into that. Then, in elm or pine, you can
insert the message with a simple command (control-R in pine, for
example); only this time you won't see all that extraneous stuff.
* You haven't cleared out your Elm mailbox in awhile, and you
accidentally hit "y" when you meant to hit "n" (or vice-versa) when new jersey flash designer
exiting and now all your messages have disappeared. Look in your News
directory (at the command line, type: cd News) for a file called
recieved. Those are all your messages. Unfortunately, there's no way to
get them back into your Elm mailbox -- you'll have to download the file
or read it online.
Chapter 3: USENET I
3.1 THE GLOBAL WATERING HOLE
Imagine a conversation carried out over a period of hours and days,
as if people were leaving messages and responses on a bulletin board. Or
imagine the electronic equivalent of a radio talk show where everybody
can put their two cents in and no one is ever on hold.
Unlike e-mail, which is usually "one-to-one," Usenet is "many-to-
many." Usenet is the international meeting place, where people gather to lan flash designer
meet their friends, discuss the day's events, keep up with computer
trends or talk about whatever's on their mind. Jumping into a Usenet
discussion can be a liberating experience. Nobody knows what you look or
sound like, how old you are, what yo ... |
