I propose useing aliases since getting user (or yourself) used to a
"safe" rm is a bad idea. Imagine telneting into a fellow's system and
rming without really considering the risk...

alias rmi='/bin/rm -iv'
alias mvi='/bin/mv -iv'
alias lni='/bin/ln -ivs'
alias rm='echo Please use rmi or /bin/rm ! Used parameters: '
alias mv='echo Please use mvi or /bin/mv ! Used parameters: '
alias ln='echo Please use lni or /bin/ln ! Used parameters: '

Subject: ASedit 1.2 & Motif
Date: Mon, 7 Mar 1994 17:20:48 GMT



Has anyone noticed any strange behaviour with LINUX and ASedit 1.2?  It
compiles beautifully with MetroLink's Motif 1.2.3, but after a little use,
the editor seems to kill all mouse events.  I am unable to bring any other
windows into focus, I can't even call up the root menu under mwm!  It ends
up hanging the X server, and I have to re-boot.  Has anyone noticed anything
like this happening with other Motif programs?  I'm trying to determine
whether this is a Motif problem or just ASedit.  The author of ASedit says
he's 'mystified' as to why this would be happening, so it seems like an
unexpected bug....


Thanks for any help/advice, I'd appreciate e-mail responses if possible
since I can't get onto these groups as much any more...thanks!

Subject: Cheap SCSI tape drive
Date: Tue, 8 Mar 1994 01:58:32 GMT


old SCSI tape drive:

Takes standard DC300 style tapes, gets about 50 megs/tape and reads at
75K/second. While it doesn't store more than the floppy port drives it works
alot faster. I'll also throw in a couple of used (but still useable) tapes.

I've tested the drive under Linux, its at SCSI ID 4 (there are dip switchs
which you could change this with if you feel like playing.)

The drive is 1/2height and has a small external controller card which
has about the same horizontal dimensions as the drive, you could probably
rig it into an extra drive bay, or something.

Actually, I do not want to panic anybody, but this is exactly what is

Obviously Linus grew tired of all the abuse of his name and has put some
digitized data in the kernel proper. Also, the copyright for 1.0 will
change, so that one is only allowed to use Linux if one uses the correct
pronounciation.
And although I am really outraged about the imposed kernel bloat, I
think it is only fair to let you know, that this article is a cruel hoax!

I think the bottom line is: If you want to be correct, you might have to bend

Hello all - I was wondering if anyone could comment on the stability that 
Linux offers running the ex2fs and/or the xiafs file systems?  Do they tend
to operate well under pressure, etc?

What is MOST likely to happen if say the system suffers a power-outage 
while doing disk-intensive processing.

Any help/technical info would be GREATLY appreciated.

Subject: how much memory to avoid swapping?
Date: 7 Mar 1994 15:46:39 -0600

I seem to remember a couple of posts a while back about how much
memory linux requires to avoid excessive swapping.  As I recall,
the concensus was that 16 MB wasn't quite enough, and that about
20 MB was required.

Is this correct?  Does that number go up for a full installation,
i.e. one including net-2, etc?

I am buying a PC to use as a linux machine, and I need to know how
much memory to order.  I may not have enough cash to get it all
now, but I'd like to know what I'm shooting for.

Thank you for you help.

        This sounds exactly like what happens with Mosaic, compiled with
Motif 1.2. I found a way to consistantly produce the bug by trying to move
the scroll bar while Mosaic is downloading something. It locks up X input
every time.

The Slackware distribution uses a different color-ls patch, but the
patch I'd recommend is on sunsite, color-ls-3.9.0.2.patch.gz in the
/pub/Linux/utils/file directory.  It's a diff off of fileutils-3.9,
and is more flexible than other patches: you can define a COLOR_LS
(or COLOUR_LS for people on the other side of The Pond) variable to
customize your colors, in case you don't like my preferences, and you
can have colors turned on 1) always, 2) never, or 3) when stdout is a
tty.

It also lets you turn on 8-bit filenames, and unifies the ls, dir, and
vdir programs into one binary.

This patch was written by H. Peter Anvin (hpa@nwu.edu) and me, with lots
of suggestions and cooperation from other Linux users.  An lsm entry can
be found next to it.  Since it's a patch to the gnu standard fileutils,
it can be patched for any other system which accepts the standard color
escape sequences.

Please do not post questions to comp.os.linux.misc - read on for details of
which groups you should read and post to.

Please do not crosspost anything between different groups of the comp.os.linux
hierarchy.  See Matt Welsh's introduction to the hierarchy, posted weekly.

If you have a question about Linux you should get and read the Linux Frequently
Asked Questions with Answers list from sunsite.unc.edu, in /pub/Linux/docs, or
from another Linux FTP site.  It is also posted periodically to c.o.l.announce.

In particular, read the question `You still haven't answered my question!'
The FAQ will refer you to the Linux HOWTOs (more detailed descriptions of
particular topics) found in the HOWTO directory in the same place.

Then you should consider posting to comp.os.linux.help - not
comp.os.linux.misc.

Note that X Windows related questions should go to comp.windows.x.i386unix, and
that non-Linux-specific Unix questions should go to comp.unix.questions.
Please read the FAQs for these groups before posting - look on rtfm.mit.edu in
/pub/usenet/news.answers/Intel-Unix-X-faq and .../unix-faq.

Only if you have a posting that is not more appropriate for one of the other
Linux groups - ie it is not a question, not about the future development of
Linux, not an announcement or bug report and not about system administration -
should you post to comp.os.linux.misc.


Comments on this posting are welcomed - please email me !

You can get rstatd (written by perf's author Rudolf Koenig too) at
this location:
        ftp.uni-erlangen.de:/pub/Linux/LOCAL/rstatd 
if your system supports identd, or at:
        epix.rrze.uni-erlangen.de:/pub/Linux/LOCAL/rstatd

You need rpcgen(1) to build rstatd.

Hope this helps, Th.

        I have a 386DX 40Mhz running linux and Toshiba T1000SE.  I'm pretty

an external hd (about 40 meg or so) and put minix on it, and nfs connect it to

anyone know how I could use it as a dumb terminal across the parallel or serial
ports?  What sort of program should I use?  Any idea's would be appreciated.

Hmmm.  Last time I tried straight "gcc", it failed to convert some
trigraphs for me.  (Yes, I know that there's a flag somewhere to
make it recognize the damned things.)

Chances are that SunPro's C compilers for Solaris have better ANSI
compliance than gcc, and certainly no worse.  (I worked for SunPro
last year, so I do have some bias).  The SunOS (4.1, 4.1.1, 4.1.2,
4.1.3, 4.1.3c) products are hindered somewhat by bogus system include
files, but SparcCompilers 2.0.1 has very few bugs, and SC3.0 had even
fewer (perhaps zero) when I left Sun as that product was beginning
beta-test.

GCC may have a more dispersed set of testers, but I rather doubt that
there is anyone (except perhaps at Cygnus) who tests it 24 hours a day. 
At SunPro, we (where "we" is four separate teams for which
compiler-testing was part of their job) ran tests more or less 24 hours a
day, and no failure was ignored.  I'd start tests when I went home at
night (typically, I'd start two or three threads of tests) and the results
would be ready for me to look at in the morning.  When I went on vacation
for a week, I'd fire off enough testing for one week (and if you've run
all the tests, then you can try them again with weird compiler flags).
If we had alpha or beta-test hardware from SMCC for various purposes,
we ran tests on it when we weren't using it for "various purposes".
We ran tests on different versions of the OS, just in case (and
sometimes this mattered).  If it was necessary to test an alpha or beta
version of a new OS, we ran compiler tests to generate background
load.

That was just me.  Other people in the compiler team tested similarly. 
The people working on parallelizing code ran a different set of tests. 
The people working on floating point libraries ran yet another set of
tests.  The people whose job title was actually "testing" performed even
more tests, with code coverage.  In my spare time, I went looking for
code to compile out on the net, just to see how we did.  (Last I heard,
using a piece of GPL'd code as compiler test input did not cause the
compiler to become a "derivative work".)  (And yes, there are some
incompatibilities with some of the code that is out there, but it
usually involves asm statements.  Sometimes in involves syntax errors
that are forgiven by one compiler, but not by another).

Sorry to be so long-winded, but I get the impression that some people
think these products are just tossed out the door when it suits someone's
whim.  This is certainly not the case for the compilers that I worked
on at Sun, and I believe that similar attention to quality exists at
other workstation vendors.
