Message-Id: <34F592F8.15F2@nbnet.nb.ca>
Does anyone out there have any experience with using perl in a
Windows 95 environment. Everything in the script and html code
seem right, but for some reason when the Netscape browser runs
the cgi file it finds the .cgi file but will not execute the
Perl script in there. Yet running the perl script through DOS
shell and the script works fine. :(
It is as if it cannot find the perl.exe. My question is has anyone
else run into this problem and do you not of any bug that might
be causing this (wetware or software related)?
I am currently using a copy of PERL5 from the SAMS "Learn Perl
for Windows NT" book.
Thanks in advance.

I am trying to clean up an old script written in Perl4, and convert it
to Perl5. For instance, the first few lines are:
push(@INC,'/usr/local/lib/perl5');
require "/usr/local/lib/perl5/cgi-lib.pl";
Question 1: Is there any benefit (speed of execution) to changing this
to "use CGI.pm;"?
Question 2: Are there any pitfalls I should be aware of?
Question 3: It uses &ReadParse(*input) to gather data submitted from an
HTML form. Will I have to basically re-write the entire script to
conform to CGI.pm?
Thanks for any help!

We've got a perl interface to our C++ program. The problem is that we
cannot step into the perl code and interactively debug. We've had to
resort to using 'print' to figure out where any errors in our perl
script might be. Has anyone found a way to interactively debug a perl
script from a C++ debugger? We're running on Solaris, SGI, HP and NT so
if anyone has any clues on any of these platforms I'd greatly appreciate
it.

Good faith effort to tell people trying to post to the group I moderate
why I am rejecting their posts? (Eg. no uuencoded posts.) Simple question
I can answer but is not topical in the newsgroup I saw it? (Eg. MIME
questions in comp.editors.) Simple question I can answer that is a tedious
FAQ in the group I saw it? (Eg. Checking for valid email addresses in
comp.lang.perl.misc.) Good faith effort to answer some question on the
procmail list? (People there seem to be intoxicated with the powers of
that filtering program.)
Recently I have been getting five to ten bounces a week on twenty to
fifty pieces of email a week, mostly (I suspect) post rejections.

This is meaningless. Lexical variables are not in any package, and

The thing you're missing is that lexical variables are visible in the
block where they're declared and *in all blocks nested within it*; ie
nested blocks 'inherit' lexical variables from the blocks that enclose
them. Once you realize this the code above makes perfect sense.
Whether a subroutine can see a lexical depends on where the sub's
definition is, not where it's called from. Clear?

you can get the output from practically any system command this way:
@output = print `SYSTEMCOMMAND`;
Therefore, you could try @df = print `df`;

Here is part of a script that I wrote. Works on Perl 5 running DG/UX.
This script (basicly) reformats the output of df -k and sorts and totals the
columns.
The code may not be a Perl wizards dream, but I just got here myself.
open(DF, "df -k|"); # run the command DF and get the output
# read the first line, this is the title line
$title = <DF>;
# now read the read the rest
@drives = <DF>;
If you want the whole script, let me know.

Do you need to find out what's in between just for curiosities sake?
Put the output into a file and type:
cat -v file
This will display all control-characters in octal so they stand out.
It may not really be spaces there. Might be control-w's or some such
nonsense. If you need to split, rather that splitting on explicit
spaces, try splitting on Whitespace. There's a special perl Regular
Expression metacharacter for matching whitespace, and is quite portable:
split(/\s/, $stuff)
This will split on a single whitespace. To split on multiples, use /\s+/.
PS:
If you don't have cat, here's a nickle kid, get yourself a real
Operating System.

Message-Id: <34f581db.1776965@news.interport.net>
I have a flat file database which is accessed from a search form via a
perl script. I was wondering if there is a built in limit in perl on
the size of the records. If so, where could I get info on how to
divide the records? Would I have to go to a relational database to
handle large records.
The database is basically an address database but includes html links
if they exist. It includes multiple cities and zip codes for some
records. I would also like to be able to include a multiline
description field of matches to the query. Thanks for any advice.

comp.infosystems.www.authoring.cgi (I think) is a 'self-moderated' newsgroup. All
posts get a standard reply, including pointers to FAQs et cetera, asking you to
reconfirm your post. My one and only post to that group, asking where the FAQ was
never got there to annoy anyone.
This would deal with all but the most wilfully silly posts. The only doubt I have
is whether those who spend a lot of time responding to this group find it an
unacceptable overhead.

I think it should be posted daily. I often need to find out things very quickly
and can't always spend a week or a month lurking until the FAQ appears.

Why are you splitting on the number of elements in the
array? I promise you that there won't be newline pairs in
the 23 or 71 or 4 that you get back. And what's the /s doing?

I shall not. Your slashes are wrong there. Flip them. You have done
something that isn't what you think. "\tmp\foo" has a tab and a form
feed in it. Go see the FAQ. And the basename module will handle much
of this for you.

Subject: system(command) = fork + exec(command)? kill parent, children?
Message-Id: <6d3uos$n4u$1@news.ml.com>
If system(command) = fork + exec(command),
then how can I get the PID of exec(command), not the
PID of the system(command) which is the parent of
the "command".
The reason I need the PID of exec(command) is that
I want to kill the PID of exec(command), not its parent.
This also brings up another question. On unix (solaris)
system, what happens to the children if you kill the
parent? becomes zombie or killed as well, and what
determines what will happen? Thanks.

You mean besides the ways listed in the standard perlfaq8 manpage
shipped with every version of perl since 5.00 and which should
be sitting there right on your very own system?

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.
