Well, we do a lot of perl cgi development on our P133. Whenever I am testing
stuff and occasionally forget to end a loop the INETINFO process just goes
straight up to 95% or so and the ONLY THING TO DO IS REBOOT.
It's a real pain - Does anyone know of a good way to "HUP" the process or
somehow convince it that I don't really want to continue with the infinite
loop??? :)
Thanks much for any help!

I've got a kill-and-restart-inetinfo.cmd file that I use. Something
like this:
@echo off
kill inetinfo

Subject: accessing parallel port in perl
Message-Id: <64jec6$ti$1@news.nsd.3com.com>
Howdy,
How do you access the parallel port on a unix machine (Solaris in this
case) from perl? People have told me to treat it like a normal
file and open() it, but I'm not sure how that would work to access
data on specific pins of the parallel port.
I am trying to read/send data on a Dallas Semiconductor DS1620 Digital
Thermometer. Basically this circuit hooks up to the parallel port
and allows you to read the temperature from the device. It hooks
up to pins 4.5,17 and 18 on the paralel port, 4 and 5 being data.
I have the specs for the data I should get from the parallel port, but
I can't get to the point of getting data yet!
Any pointers on how to access data from the parallel port would be
greatly appreciated.
Thank you,

Subject: downloading a file using perl from lynx
Message-Id: <346DFDFF.B0C@earthlink.net>
for my website, i need to download many files, mostly over 1MB in size.
i'm on a slow modem and so use my shell's speed to download most of
them, which means opening lynx and copying the url over and waiting for
it to download then save.. this is ok but not very efficient. what i
would like to do is either have a little form on a page where i can put
the url and send and the server will download or have a little line in
the .cgi that users already send that would hopefully be as simple as '
download http://blah.com/blah.exe ' so that the file will be all ready
when i need it.
i suppose if i do ' lynx http://etc.. ' from the .cgi it will load up
lynx, but i dont think it would download, because usually i need to type
'd' to start downloading and then it probably would save it.
anyhelp would be nice! -- please CC to my email

[--- snip ---]
I don't know if the following will work for other than text files, but I think
what you want is something like 'lynx -source ...' this usually drops the
HTML source for a given page. I think it might work for any file out there.
I frequently use 'lynx -dump ...' and 'lynx source ...' for standard jobs. The
former gives the interpreted page (as it looks when viewed) whereas the latter
is the source.
Hope it helps

Just print it out before you start processing, be sure to have

Subject: Multi-threading Perl interpreter?
Message-Id: <64loh6$s0k@masters0.InterNex.Net>
Hi everyone,
I am trying to embed a Perl interpreter (5.004_01) in a software. I want to
run multiple Perl scripts in multiple threads. I wonder if anyone knows how
well the existing Perl interpreter supports multiple interpreter instances
in a process. I want to do it because I want to ensure total isolation of
name space and state of Perl library packages.
I tried instantiating multiple Perl interpreters in a process and I got a
crash when it tries to clean up. I heard that Perl interpreter
implementation is still not thread-safe yet. However, I heard some people
claiming success in doing so. Any suggestion?
Thanks.

That would be because the script is sending its output to the server,
not the browser, and somewhere in the process the output is being
held in a buffer. Maybe unbuffering standard out will do it for
you, maybe not.
For better results, use a non parsed header script.
By the way, this isn't a Perl question.

"non parser header" doesn't mean unbuffered by the server; in fact the
script communicates directly (bidirectionally, potentially) with the
browser.

Hi John!
Server executes script and waits for script to finish
before sending output to your browser..
This script will not finish until after 300 sec. Right?!

Consider installing a web server on your machine. I've been testing my
MacPerl CGIs with Quid Pro Quo, a good freeware webserver. You can
download it from Social Engineering's website
<http://www.socialeng.com/>. (They also offer a commercial version, Quid
Pro Quo Plus, but the freeware version will work just fine for what you
want.) It's about a 2 Meg download.

Subject: two machines dealing with script differently
Message-Id: <347202d7.19449351@news.ais.net>
Ok, here's the scenario:
Two Sun Sparc 10's. Both identical in configuration. I have a script
that reads in data from a log file, then compares the new data to the
log. The log is reopened and each line from the original log is
compared to the new line of data. If the line matches, it prints to
the log and adds 1 to the number of times that line was found. If the
line is not found, it just rewrites that line of the log back to the
log. Problem is, it increments correctly on one log, but not on the
other. I can start out with a list of data in a log on both machines,
say:
hi|100
by|90
joe|50
sam|20
Then after it ran for a while, the one machine will have increased the
numbers, the other one will actually have numbers lower than the
orginal log. Any ideas?

See the perlop manpage for alitle of operator precedence. || has a
higher precedence than = but or is lower than it.

In my experience who does that for you. Now I admit most people have
never devised ways to check this or used the ways availible (rsh comes
to mind) so caution is reasonable.

Lots of sites have disabled that. Eg:
:r! lynx -dump gopher://panix.com:79/@
Panix does not reply to non-specific fingers.
Please specify a specific user to finger: user@panix.com
For more information about Panix, email (or finger) info@panix.com
If they haven't, a redirect to that gopher protocol hack might be
better than `who` in a CGI.

qw looks for whitespace as the separator. Remove the commas.

You probably want "cperl-mode.el" - theres a "perl-mode" too but cperl
seems nicer.

Message-Id: <null>
Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
