Ooh ooh, I have an anecdote! (longish)
When I was at my undergrad university, my lab had a PC, and we used
something called ProComm (a terminal application) to connect to the
"system" (and the internet/web). At that time, I knew relatively
little about computers. Anyway, ProComm was how I got my email;
otherwise, I'd have to go CLEAR DOWNSTAIRS to login. One day,
I suddenly couldn't type anything. So...I thought I'd just kill
the connection, then log back in (sysadmins just LOVE when you
leave runaway processes running, anyway--try it sometime!). But
this time, I couldn't log back in; the prompt wouldn't even appear.
Normally, I'd just wait till the grad student in our group fixed
it; however, he was gone for a week. So, there I am, unable to access
my email for three days (well, without walking CLEAR DOWNSTAIRS...).
This was harsh, as I was running a laser in a dark room, nothing else
to do but read USENET, etc..
So, after three days, in desperation, I went to plead my case to
the sysadmins. Ever the friendly people, one of them trekked back
upstairs with me--on the other side of the building--to see if he
could fix it. He walks into the lab, takes one look at the computer,
hits CTRL-Q, and the terminal magically awoke!! He just kinda grinned,
then explained all about blocking the terminal input, and how they
hopefully would get rid of those orange cables soon.
(BTW I believe I hit CTRL-S when trying to save something
in emacs.)

You'll also notice the ScrollLock light coming on. Linux is one of the
few OSes to actually use the ScrollLock for what it was intended.
(Some applications have used it in the past for sometimes bizarre
purposes.)

are you doing this as root? Usually only root can see things in the
sbins directories. Also, it could be that you don't have permission to
use one of those commands, or bash can't find it. Often times bash just
says file not here when its one of the calls made in the file your
executing.
Is the first line of this file:
#!/bin/sh
?

Fetchmail should do what you want. It will pull mail from POP3 servers and
send it to local mail spools of folders for you to read with the e-mail

Hi-
I'm trying to write a script that will choose an editor for mutt based on
my enviroment.
If at the console I'd like to use vim
if using x11 then nedit
The use of the DISPLAY variable wont work because that could be

Is there maybe a XSESSION variable?

There is builtin assembler in the gcc. Really GCC does translate into
assembler first, and then invoke the GNU assembler to produce actual
binary code.
But this assembler have completely different syntax - arguments are
reversed and some special chars like % are used to denote registers.
However I doubt that assembler on Linux worth learning for you.
Direct hardware access is prohibited by OS protection mechanism anyway,
all system services are available as C functions and GNU C optimizer
does good job on computational algorithmes, so there are few chances
that you could write faster code than GCC would do for you.

But DISPLAY should not be set if there is no display. It is wrong
to set it elsewhere.
Anyway, you could try to run some program that requires that X be
available, for example
if xrdb -query > /dev/null 2>&1 ; then
# it worked; X is available
nedit "$@"
else
vim "$@"

There is no standard way to combine two filesystems into one;
you must decide how you'd like to do it. You could have
/mnt/raid/home and /mnt/raid/var, and make symbolic links from
/var and /home to those places, or you could mount the raid
device on /var, move /home to /var/home, and make a symbolic
link from /home. There must be other (reasonable) possibilities,
too.
Once you decide, the general recipe is something like
1) mount the new device somewhere (temporary)
2) copy the filesystem(s) from the old to the new place
(you can use cpio, tar, cp -R, or some other program;
cpio has the best reputation for this purpose)
3) edit /etc/fstab
4) umount the old device(s)
5) mount the new device(s)

My face is all red now *blush*
Looking at my fstab just then, I realised that
/usr/local
had an entry before
/usr
This is the cause of the problem.
I never once saw any errors mounting local filesystems when booting though.

First defrag your MS OS so that all the data in the hard drive are moved
to the front portion of the partition.
Next, boot to DOS mode and use the FIPS in the RedHat 5.2 CD-ROM
\dosutils\ directory to split the partition into two. You can specify
the size of each partition.
Next, run the Linux installation from the RedHat CD-ROM. It is very
convenient if your system allows booting fro the CD-ROM. The Linux
installation process will load a Linux Loader program (lilo) which acts
like a boot manager. This allows you to choose the OS to load during
booting.
When "lilo boot:" appears the next moment you re-start the PC, press
<tab> key to see the available OSes which you can choose.

Did you receive an error message? Perhaps the installation procedure

This should fail since CD ROMs are read-only.

The big difference is that since virus only has write permissions to
your
home directory, it can't infect system-wide setup, thus it will not
spread
to other users. It would also not be able to infect document templates
and
thus would be somewhat confined. It's not complete protection, yet
better
then virus having full access to your whole system.

The issue was that glibc-2.1 had to be compiled by egcs, not
gcc-2.8.1. The problem is going away because (1) glibc-2.1.1
will be compatible with gcc-2.8.1, and (2) the egcs team is
taking over gcc maintenance. You can find the source code
at ftp.us.kernel.org/pub/software/libs/glibc.

It uses symbols internal to the glibc-2.0 implementation that
were improperly exposed to user programs. These symbols are no
longer available in glibc-2.1. (The glibc people say that these
symbols were never documented as being available for use.)

I have to agree with Jim here....i think it would be a little farfetched to see
the enterprises as fascist coorporations (fascism is the adoration of violence,
fascist see violence as the only way the rule a country, also part of fascism is
that those who use completely any class differences in their society).....i do,
however, think that the USA as a whole is a fascist/police state, that could also
be because of a wrong image that i have of the usa ( because of tv perhaps), but
that is how most people i know think about it, and that is the image that
america's international politics give me ( Serbia etc.....)
