Yes, SuSE rocks. It is pronounced SuSE, like the word moose. A friend
of mine uses the same distribution, and yes he is German. Ha Ha I think
the German translation is SuSE(like the word moose), or simply like
soose(SuSE)

Date: Wed, 23 Jun 1999 18:57:40 -0400
Anyone remember Word Perfect for DOS? I found a package that was made
back in 1984 or so that had only the file manager. It was nothing at
all, really, but it was quick, easy to use, and very intuitive. It
included basic commands only (copy, move, change active directory,
things like that). Is there something like that for a linux terminal?
Or do I need to learn C and write one? :)
Just to let you know where I'm coming from, I was really irate when
everyone started using Xtree Gold, I thought it had too many options. :)
Would there be a market for this if I were to write one? Do you think
people would use it?

Migrate to integers if you want precision. As a saying goes: you didn't
understand the problem if you cannot express it with integers ;)

Oh yeah, excellent idea. May I suggest to mutilate the root account, too?
Please check the UNIX FAQ why having the CWD in the PATH is a bad idea in
the first place.
But having it at the beginning(!) of the PATH is like playing Russian
roulette.

Good point. Just make sure to 'chmod u-s' them until you actually
need to use it. suid perl scripts aren't that common, and to have
suid programs when you don't need to is a bad idea.

The important things are whether it is plugged into a parallel port or
a SCSI card, and if parallel, how new your Zip drive is. Older Zip
drives are well documented in the how-to. The new ones use the imm
driver. This is usually available as a module, but you need to load
it using insmod or modprobe (see manpage for more details) before you
can use it. If you have a disk in the drive when you load the driver,
the system will read its partition table, and a command like 'cat
/proc/partitions' will show the structure of this drive along with all
the others that you already know about. The drive appears to the
system like a SCSI disk, and Iomega formats the disk so that it is the
fourth partition (even though the first three don't exist). Once you
have the correct name in the /dev directory, you can mount it like
anything else.

:Probably not knowing Linux,
If that's your premise, I have bad news for you: it's wrong, and as
we all know, a false premise can generate any number of irrelevant and
unverifiable conclusions. :-)
:you might not know that all of these
:"splinters" are using the exactly same kernel, the exactly same
:utilities and the exactly same libraries, even though the currentness
:of the versions might differ.
I have installed many different versions of Linux, for many years,
time and time again. And I assure you, they are *very* different.
It's undeniable.
:They differ in their installation
:procedures, the extent of included applications, the choice of
:desktops and a few other trivialities.
You have a radically different notion of triviality than I do!
Application presence and compatibility (read: programs; read: utilities)
are the farthest possible thing from trivialities. In fact, for
virtually everyone, they're all that matter. And you can't count on
them *in the least*. It's nothing short of maddening.
I once had a fricking RedHate system claim to be installing for a
"server" (whatever that meant), newfs my disk (which was fine), and
then not bother to install a dump program -- or more importantly, a
restore program! Hello? Knock knock knock. Is there anybody home?
What the hell were these people thinking?
Or what about the time that xterm -C made the system unbootable due to
a bogus pty link? (Yes, I guess we can blame someone else for that.)
Or what about about the time a Linux distribution install new dynalinked
utilities and then crapped out for lack of disk space before they could
get the libraries in? That was lots of fun, too.
Then there was upgrading the kernel and all the ptys breaking, and there
being no MAKEDEV script.
And no fricking manpages for anything you need to have. The shame!
Don't get me started. And that's really just the bare start of it.
It's a horribly tangled mess, and I could go on all night.
Do I have something good to say? Why, yes. I do. It's my hope and
belief that the ramifying balkanization of Linux we're now seeing will
improve this terrible situation, because real people won't put up with
this bullshit, and it's a competitive advantage to get these things right.
If I had had anything to do with putting out a Unix distribution as shoddy
as some as these have been, back when that used to be my job, I would have
not only lost my job, I likely would have been held criminally negligent
as well. And if I had given one of my (multi-million dollar account)
Unix customers something as different as is one Linux distribution to
the next, he would have personally ripped my fingernails out and used
them to eviscerate my eyeballs with.

I can use the WinNT server manager to access stuff on my Linux computer.
This comes with the new samba (2.x.x). I can see who is on the Linux

the way of NT admin from Linux. I don't even know if this is what you were
