Subject: launch a DOS program from a Perl script?
Message-Id: <1194737404.750582.63550@50g2000hsm.googlegroups.com>
Can I launch a DOS program from within a Perl script?
____
This is what I need to do:
I have many files like this:
c:\dir\pippo-red.html
c:\dir\paperino-yellow.html
c:\dir\pluto-red.html
c:\dir\gastone-green.html
I have a HTML2TXT.EXE program that converts files from html to txt
(removing the tags etc...).
The syntax of this program is: "HTML2TXT htmlfilename.htm >
txtfilename.txt"
I want to convert all and only the file which path-name match "c:\dir
\*-red.html". The output files must have the suffix "-text" in the
filename and ".txt" as extension.
In a few words the Perl script in this example must execute the
command two times like this:
HTML2TXT c:\dir\pippo-red.html > c:\dir\pippo-red-text.txt
HTML2TXT c:\dir\pluto-red.html > c:\dir\pluto-red-text.txt
Do you know how can I do this?
Thanks in advance for any help

This seems to be the solution:
system "HTML2TXT $_ > ".(/(.*)html/)[0]."txt" for <c:/dir/*-red.html>;
but how can I launch it from command-line?
I tried PERL 'system "HTML2TXT $_ > ".(/(.*)html/)[0]."txt" for <c:/

I would have thought so too, but it didn't work for me.
(I'm using RedHat Enterprise Linux 4. I deleted
/usr/lib/perl5/5.8.5/Scalar/ and reinstalled Scalar::Util. I still get
the same error message.)
Any help on this would be greatly appreciated. How can I get an "XS
version"?
Thanks, Philip.

When Paul mentioned "reinstalling Scalar::Util" he meant that the
reinstallation be done by building from the CPAN source distribution
of Scalar::Util. Is that what you tried ? (Reinstalling an RPM
wouldn't help if the RPM package is not an XS build.)
Even then, building Scalar::Util from source won't give you an XS
build if a C compiler is not found - in which case (I think) you'll be
informed, during the build process, that you're not getting the XS
build.
Cheers,
Rob

You need to do some research on the TCP protocol. You are confusing many
different things together and it is clear that you have no clue how TCP
works. I don't think you really know what you need to do because if your
app is not behaving as you expect it on localhost, changing buffers or MSS
sizes is not going to fix your problem. Since you haven't described the
problem you are trying to solve, I can only guess that you are having issues
with data written on the socket is not being sent out in a timely fashion.
You are guessing (wrongly) that this is a buffer problem, it is not. If you
are writing to a TCP socket and the data needs to be sent out immediately,
you need to set the TCP_NODELAY option.

The data and chart generation Perl program (4000 lines of code) that I have
running works quite well. The next major step is to learn how to save the
main program as a .exe file. I have a "Par" module already merged with
Perl. But I have not had a chance to learn how to use it.
The Gif file generation module does generate nice charts. But for some
reason, some of the data displayed on the original chart are not appearing
on the Gif charts. So I have been sending the Perl screen charts to the
clipboard and pasting them to the Windows Paint program which is then used
to produce the Gif files. When time permits I plan to try to determine how
to get the Perl Gif module to copy all of the data to those files.
These are difficult programs for professional programmers to work with
because they involve so much research. Each improvement indicates what
needs to be done next. I never know beforehand exactly what the next
routine to be added is going to be. So it is almost impossible to make
plans for how to structure the main program. Things keep changing. If and
when everything gets settled the main program will probably be duplicated in
a more organized form by more highly skilled programmers. It is fortunate
that Perl is sufficiently versatile that when important changes are needed
they can be made without too much trouble.

None of the programs I have been able to find on the Web appear to have all
of the features that are needed here. And I am going to explore this
further in some of the astro and astrology newsgroups.
As already mentioned, another researcher and I have written a TrueBasic
program that will do what is needed. But it will have to be thoroughly
tested before it can be used to replace the U.S. Navy's MICA program that is
presently generating the needed data.
My data indicate to me (and more and more international researchers are
agreeing) that sun and moon gravity related effects are quite important to
determining the times when earthquakes occur. Ocean tide and Solid Earth
Tide effects also appear to be important. Considering how much damage
earthquakes can produce, it is amazing to me that our governments and major
research groups have not already made these types of data generation
computer programs available for researchers around the world to use.
These are personal opinions.

Thanks for the recommendation.
Another researcher/computer programmer and I already have all of the needed
equations. And we have a program running with the TrueBasic language which
does what is needed. I was checking to see if there might be any new
software out there that has already been tested and proven to be totally
reliable.

You're right, I haven't used that one. @array[-5..-1] is pretty useful
