Try:
mt -f /dev/nst0 fsf #Forward space file
to move the tape to the second tape file. Then you can either use tar to
extract the archive or dd to copy it to disk.
(Note: BSD used to put two EOF markers at the end of a tape file requiring
one to use mt -f /dev/nst0 fsf 2 instead, but, IMS, I do not think that
Linux does that, FWIW.)

This is described in detail in the Boot Prompt HOWTO, and mentioned in
the Ethernet and SCSI HOWTOs. I suppose I should add it to this week's
rev of LILO mini HOWTO.
boot prompt: linux root=/dev/hda5
You can't use a "raw" bootimage floppy for this. You need a loader
that will prompt for a boot command line. If your distribution made a
raw bootimage disk, use your installation disk or a Debian Rescue Disk.

Subject: Compiling KDE apps; Linker error
Date: Fri, 10 Sep 1999 15:44:05 GMT
Greetings gurus.
I'm trying to install the K-debugger on my RH6 box from tarballs but I'm
getting a very annoying error messages from the configure scripts (in
fact from __every__ configure script that links with kde and qt.)
"checking for KDE libraries installed... configure: error: your system
fails at linking a small KDE application!
Check, if your compiler is installed correctly and if you have used the
same compiler to compile Qt and kdelibs as you did use now"
This I have done; downloaded the KDE library sources (both 1.1 and
1.1pre2), compiled and installed them without trouble, downloaded,
compiled and installed Qt (both 1.44 and 2.0) without trouble, set the
KDEDIR, QTDIR, QTLIBDIR etc. etc. env.variables, and messed with the
configure script till I was blue in the face. Following is the error
part of the config.log:

Subject: Linux, Windows, and cars
Date: 10 Sep 1999 21:02:38 GMT
Reply-To: [EMAIL PROTECTED]
I've been following the "Rant From A Linux Newbie" thread. I've
decided to add my comments under a new header.
First things first. I'm wondering if someone should create a
newsgroup called comp.os.linux.newbie.rant. My first couple of
months with Linux were incredibly frustrating. There was so
goddamned much to learn! Seemed like for every simple task
I wanted to accomplish, I had to wade through twenty
incomprehensible man pages. More than once, I wanted to post
to this newsgroup, calling Linux all sorts of nasty names.
Of course, now that I've been doing Linuxing for a while, I read
rants from newbies (the same rants I might have been tempted to
write myself) and smile with fond indulgence. Oh yes, I still
remember. Linux isn't easy on newbies. They need to blow off
steam every once in a while.
Secondly, I'm getting tired of the Linux vs Windows debate (who
isn't?). Linux doesn't exist in order to "kill Windows." Linux
exists to offer an alternative OS for those who require (or
would simply prefer to have) the tools it provides. You can do
some amazing things in Windows, or so I've heard. (Never used
it myself. <g>) You can do some amazing things in Linux. For
that matter, you can do some amazing things with a Mac or an
Amiga. Why do so many people measure Linux's success by it's
"better-ness" instead of by its innate "terrific-ness"?
Lastly, I read a lot of posts likening OSs to cars. I think
it's time we dropped the analogy, especially in reference to
Linux. A much better analogy (if not so neat) is that of
carpentry.
Say, for example, you decide you want to remodel your kitchen.
If you have money, you pay someone to do it for you. No
problem. It's a luxury you can afford, and no one expects you
to understand everything the carpenter does just in order to
store canned truffles in your new cupboards.
But say you don't have money to spare, and you still need to
redo the kitchen. Well, then, you bite the bullet, learn
everything you can about carpentry, find some wood (cut it
yourself?), and set to work. In the end, you've got a kitchen
probably just as nice as the one built by a pro, and you haven't
been forced to lay out cash you don't have. As an added bonus,
if something isn't quite right, you know how to fix it.
Windows is for those who have the money to pay for services
(and, by extension, to pay more money to get things fixed).
Linux offers an alternative, opening up the possibility of
"doing it yourself." Linux puts the power of the computer into
the hands of those who might otherwise not have access to it.
The issue isn't whether Linux is "better" than Windows, but
whether it provides users with the tools to do the same things,
at a fraction of the cost (or none at all, if you choose a
distro like Debian).

So let's say you have 1000 names in a list which need to be added
as new users to a duplicate server. With a command line and an
ad hoc script that's about 15 minutes out of your life with no
errors.
With a GUI it's about 3 days and potentially lots of errors. Not
to mention extreme boredom.
Both a command line and a GUI have their place.

I don't think that you can protect a directory based on where a user is
coming from. If this is what you're looking for, chmod isn't the right
place to search. You could consider using a restricted shell of some sort
for certain users that need access to your machine but whom you want to
keep a tight reign on. A restricted shell would limit users to running
certain programs and doing certain things, for example, by presenting a
menu-driven interface. You may even be able to find (or build) something
that started a regular shell like bash or tcsh if the login was from the
console but a menued restricted shell if the login is from a remote
terminal.

Why not? It's been useful already for a lot longer than that.

Which works well most of the time, which is why most people write most
code in high level languages of one kind or another. It doesn't
always work.

And just why not? For that matter, why is knowing English as opposed

Why is scrolling down a menu any easier than remembering a command?
People are hard wired to understand language. After a while the name
of the command becomes part of one's vocabulary, and at that point
it's a lot easier just to remember the name of the command than to
have to scroll down through a list of choices. At least that's the
case for me, and to judge by the number of people who have no trouble
using Unix, it's the case for a lot of people.

OK, using Midnight Commander, please find and compress all files in
the the root directory and all subdirectories recursively that live on
the local machine (i. e. not over NFS) bigger than 1 MB whose name
ends in ".tif". You're entitled to assume that a command named
"compress" exists.
Now let's change the rules slightly. You're to arrange that this is
done every day at 4 AM. Oh, and this is only to be done if the
filesystem is more than 90% full and if the file has not been accessed
in more than 7 days.
A little harder, yes? If you know the basic Unix commands, and
understand the rudiments of shell script, it's really very easy. And
this example's not particularly contrived; it's a very typical task
that people perform to maintain free disk space.

It's not (just) a matter of insulting one's intelligence; it's also a
matter of having sufficient expressive power for arbitrary nontrivial
tasks.

Not at all. mc makes it easy to move a directory tree from one place
to another (for that matter, I could write an mvtree command quite
trivially if I cared, and still quite easily if I wanted to make it
robust), but that is not the entire task.
Ted did already have the new ext2 partition, so that's already out of
the way, but after copying the directory there's still the little
matter of clearing out the old /misc and /home (after ensuring that
all files have been copied -- presumably mc is sane enough to copy
everything, but the Windows recursive copy seems to like to avoid
"system" and "hidden" files, if I recall, which is disastrous). Then
there's the matter of fixing up the mounts (and creating the
appropriate symlinks).

This isn't quite right, for two reasons:
1) The original poster wanted to relocate both /home and /misc, so
it won't really do to put them in a filesystem mounted under /home.
2) You can't rename a mount point.
A better sequence, after copying everything to /newhome, verifying,
and removing the old /home and /misc, is to create symlinks from /home
and /misc pointing to /newhome/home and /newhome/misc.

(assuming your NT partition is /dev/hda1).

If you knew the locations of the superblock and the copy and
the size of the superblock and you didn't get messed up by
not knowing if the counting started at zero or one, you could
in principle do that for a partition not mounted. But there
is an alternative which seems much simpler. See the e2fsck
man page.

Here are a few things to try. The descriptions are of what happens
using the particular xterm that I have, and may vary form one terminal
to another.
export PS1='\[\033[1m\]\h:\w$\[\033[m\]'
Sets the prompt to be bright.
export PS1='\[\033[5m\]\h:\w$\[\033[m\]'
Sets the prompt to be bold.
export PS1='\[\033[7m\]\h:\w$\[\033[m\]'
Sets the prompt to be inverse video.
You can also set the forground color, the background color, or
both, plus any of the above! There can be 1, 2, or 3 parameters
listed, such as these three,
export PS1='\[\033[31m\]\h:\w$\[\033[m\]'
export PS1='\[\033[31;47m\]\h:\w$\[\033[m\]'
export PS1='\[\033[1;31;47m\]\h:\w$\[\033[m\]'
The first one sets the foreground color only. The second one
sets foreground and background, and the last one also sets one
of the bright, bold, or inverse attributes (some terminals may
also have dim and underline attributes).
The colors are,
Color Foreground Background
black 30 40
red 31 41
green 32 42
yellow 33 43
blue 34 44
magenta 35 45
cyan 36 46
white 37 47
I personally like a color prompt rather than an inverse video
prompt. My xterms use a black background and a goldenrod
forground (it looks something like an amber monochrome screen),
and I use a cyan colored foreground in the prompt. Here is the
actual setting from my bashrc file,
export PS1='\[\033[36m\]\h:\u \w >\[\033[m\]'
