Some characters should not be used in filesnames because they may
have a more general meaning as directory or command separators,
piping directives, or even terminal control characters.

This is not true, check out some toolkits like GTK+
(http://www.gtk+.org) or QT (http://www.trolltech.com).

True, but this is bound to change in the future with the Xvideo (I think
this is the name) extensions available in XFree86 4 which allow for
hardware accelerated rescaling and pixmaps in alternate colorspaces such
as YUV.

Everything lacks something, but fortunately there are some interesting
things being developed for X such as antialised font rendering
(http://www.freetype.org) and a new experimental rendering engine
(http://www.xfree86.org/~keithp/render/) which implements alpha
compositing among other things.

Under any decent OS (Linux included), operations on a tempfile
are, in practice, done on a block of memory in the buffer
cache. If it is short-lived, the data may never get flushed
out to a platter at all. I doubt that the speed difference is
really noticable for most shell-scripts.
Do whatever is simplest and easiest to understand.
First make it work. Then make if faster -- but only if you
have to.

This is *very* system-specific assumption. On most Linux systems I've
seen, the root's home directory is /root , in one case /.root .

FHS suggests /usr/local for locally-installed packages, so /usr/local/sofficeXY
should be fine. On a FreeBSD system, /opt/sofficeXY would probably be the
way to go.

The last time I tried to do a remote dump, I couldn't get it to
work no matter what I tried. But that was way back in RH4.2,
so maybe it works now.
If it does, you would have to make sure the machine with the
tape gave permission. For example, you might need an entry
in /etc/hosts.equiv or /.rhosts. Unless the documentation says
something about it, you would have to experiment.

There is always a security hole. You just hope nobody else

Isn't there a saying out there that
1. There is no security hole in a perfect UNIX setup.
2. There is no such thing as a perfect UNIX setup.

Except that closing a file typically starts flushing it to disk. What you
describe is likely only if /tmp is mounted on a ram-disk (e.g. Solaris
"tmpfs").

That's the best advice.
In response to the original poster's question, the answer really depends on
the machine's configuration and load. If you use variables, but the
machine doesn't have enough physical RAM to keep it all in memory (which
depends on what other processes are also competing for RAM) it will have to
be flushed to the swap partition. These days memory is cheap, so
well-configured systems have over 100 MB of RAM (and big servers may exceed
1 GB), so if the system isn't overloaded you can probably get away with
10's of MB being kept in shell variables. However, if you keep modifying
it and storing the results in another variable, it will multiply (I don't
know how good the garbage collection of most shell implementations are --
it's probably not usually a big issue).

I wonder if you're getting some sort of spike in on the telephone line itself
which is killing the modem? That's the only thing that I am aware of that
might do it (other than the cat piddling on it <grin>). I doubt that anything
the system (Linux or NT) would do could kill it. I'm not a hardware guru,
but I just can't see any software causing some sort of modem death. I have
an external (Phoboe) modem that I've had for about 2 years now. I have never
had a problem with it & ppp. Hum, if the were external modem attached to the
same serial port, perhaps the serial port is putting out too much voltage
on occassion?
Just some thoughts,
John

Edit /etc/lilo.conf to be similar to this:
boot=/dev/sda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
default=linux
serial=0,9600n8
image=/boot/vmlinuz-2.2.12-20
label=linux
initrd=/boot/initrd-2.2.12-20.img
read-only
root=/dev/sda1
append="console=ttyS0,9600n8 console=tty0"
Notes:
the 'serial=0,9600n8' tells lilo to speak to COM1 at 9600BPS no par, 8
bits (lilo will also speak to the real video card/keyboard too).
the 'append="console=ttyS0,9600n8 console=tty0"' tells the linux kernel
to speak to both COM1 (ttyS0) at 9600BPS no par, 8 bits *and* real video
card/keyboard (tty0).
You might also want to do:
smaug.deepsoft.com% dir -l /dev/console /dev/tty0
lrwxrwxrwx 1 root root 5 May 4 19:02 /dev/console -> ttyS0
crw--w--w- 1 root tty 4, 0 May 4 18:57 /dev/tty0
smaug.deepsoft.com is my print server -- it is a 486Dx2/66. It has no
keyboard or monitor attached to it. Instead its COM1 port is wired to
an extra serial port on my desktop. Where I have:
(in /etc/rc.d/rc.local:
/usr/sbin/rconsold &
where /usr/sbin/rconsold is:
#!/bin/tcsh -f
while (1)
minicom </dev/tty8 >&/dev/tty8 smaug
end
and /etc/minirc.smaug contains:
# Machine-generated file - use "minicom -s" to change parameters.
pr port /dev/ttyS16
pu baudrate 9600
pu rtscts No
(/dev/ttyS16 is the port on my desktop that is connected to smaug's COM1
(ttyS0)).
Thus: Ctrl-Alt-F8 on my desktop gives me smaug's console.
