Hi everyone,

I am not very familiar with the UNIX market and would like to ask
a couple of questions.

1) are there any companies which teach UNIX topics such as system
   management, networking, etc? addresses? prices?

2) what are the most popular magazines in the UNIX area?

    Thanks a lot. Please reply directly to:   [e-mail]

It should have read as follows (I apologize for the error):

3. Is there a way to prepend or append characters to BUFFERS without
   (a) introducing newlines between additions (yanking to an uppercase
   buffer appends to text already in the buffer, but on a new line) &/or
   (b) writing to the file and deleting to the named buffer (in other
   words, are there ways to put characters in named buffers other than
   yanking/deleting text)?

If you're concerned about advanced Unix security, Posix-conforming
systems, or moving from Unix programming to Unix system
administration, plan to be at the Sun User Group Conference (San Jose
Convention Center) on Monday, December 7, 1992 for one of the full day
tutorials.  The Conference and Exhibition extends through Thursday.

All-day tutorials will focus on these topics and others of interest to
novice and experienced Unix users as well as Unix programmers who want
to expand their theoretical and practical knowledge.

Special offer: 5 full conference registrations (each includes a day of
tutorial) for the price of 4 when preregistering with a single payment.

Full-day tutorials currently scheduled include:
- Advanced Unix Security (Matt Bishop, Dartmouth College)
- Preparing for Disaster (a.m. - Brent Chapman, Great Circle Associates),
  plus, Why have Computer Security? (p.m. Bob Baldwin, Tandem Computers)
- Sun Network Debugging (Smoot Carl-Mitchell, Texas Internet Consulting)
- Topics in Perl (Tom Christiansen, Convex Computer Corporation)
- Programming in POSIX (Jeffrey S. Haemer, Canary Software)
- UNIX Programming Tools (Kenneth Ingham, consultant)
- The Internet and its Protocols (William LeFebvre, Northwestern University)
- Introduction to UNIX System Administration (Dinah McNutt, Tivoli Systems)
- Integrating C Code and Xt Widgets (Craig Rudlin, MD, Medical Software and Computer Systems)

If you just want to go to the exhibits, ask for a free show-only pass.

To get more information by email about these tutorials, the technical
program, or exhibits at the Sun User Group conference, send requests
to [e-mail] .

You will receive the full tutorials and program description with
registration information.  Or call 1-800/727-EXPO.  (Outside the U.S.,
use 512/331-7761 (voice) or 512/331-3950 (FAX).)

Hello,

I'm looking for a tcsh like input routine which would be callable from a C or
FORTRAN program. I just want to be able to read a line of text from the user
with tcsh-like (or emacs-like!) command line editing/recall features.

I'm working on a SPARC with SUNOS 4.1.3 but obviously the more general and
portable the solution the better!

As a bonus there would also be another routine which could modify the recall
list, but this is not essential as I could probably hack this myself given
the first subroutine.

Thanks for any help,

Karl Glazebrook.

I think GNU Ghostscript has an ASCII output option that will generate
text positioned approximately where it is supposed to be on a page
with anything else omitted.

It's non-trivial in the general case because you have to be able to handle
the entire postscript language to interpret the positioning and scaling
effects.  Plus you'll miss things where fonts have been converted to
curves and manipulated for artistic but still readable effects.  A
quick and dirty approach is to just extract the strings in parens
from the postscript and try to assemble them into text.  A more ambitious
project would be to modify the Ghostscript ascii output to maintain
some font size and type info that could be used by the speech synthesizer
to vary the output effects.

The leading program for time series analysis is probably RATS, which runs
under DOS, the Macintosh, Unix and perhaps some other operating systems
as well.

The company that writes this is located in Evanston, IL.  Their name used
to be VAR econometrics, but they might well have changed it about a year ago
(perhaps to "Estima", but I could have them confused with another company).

RATS stands for something like "regression analysis for time series" and
contains a broad array of time series analysis functions including specral
analysis.

If you cant track this down yourself, contact me by email and I will send
you the phone number.

You don't say in this post whether you're running Xenix or UNIX
and there are different tools to determine problems with streams
in each.  Xenix comes with a program 'sw', UNIX comes with crash, and
there are some freely distributed monitor programs such as u386mon
available from various ftp sites.

Xenix sw displays:

Subject: Unlocking named pipes
Keywords: named pipe
Date: 17 Nov 92 06:11:16 GMT
Followup-To: [e-mail]
To:       [e-mail]

I'm having a bit of trouble figuring out what's wrong with the
following usage of named pipes. I have 12 large compressed files which
I would like to merge/sort (they are sorted) without having to
decompress all of them before merging. So, I've written a simple script
to create 12 named pipes with mknod, say pipe1..pipe12. I begin
background processes to zcat each of the 12 files to one of the pipes
in sequence. I then start 'sort <switches> -m pipe1 .. pipe12 | <stuff> >
outputfile'.

Things go fine for a while, then the entire process freezes. The
output stream stops, and all processes go into IW wait, as if waiting
for something to happen. While in deadlock, if I try to read any of
the pipes, they each have data waiting, so all seems to be fine. So
who stopped everything and why?

Sort is able to merge at most 16 files at once, so I don't think
there's anything wrong there. Is there another anomoly in sort that
might cause this failure?

As best I can tell, sort found a depleted pipe that zcat couldn't keep
up with (perhaps sort is reading large buffers?), but no EOF, and
started sleeping. However, this isn't logical since the sort process
is followed by 3 other heavyweight processes in the pipe before the
output is written, so I would think that zcat could feed the pipes
fast enough. Besides, I thought processes would handle FIFO's normally
and sleep for at most a few seconds if it found and empty one before
hitting EOF.

By the way, in case it proves significant: I'm using SunOS 4.1.2 on a
SPARC. Standard sort, zcat, etc. Named pipes are created with mknod
-p. I've also tried sleeping for a few seconds before starting things,
with no results.

Can someone clear up the confusion, or at least add postulations to
the heap?

Please e-mail to [e-mail] or post here.
