Hmmm, I wasn't aware that isa worked with strings that happen to be package
names. I must consult the docs.

That's optional in newer versions of CGI.pm.

Has nothing to do with the version of perl you have installed; it's the
version of CGI.pm. For some reason which I don't fathom, the default is
not to do the "(offline mode..." thing when run from a terminal. You now
have to specify
use CGI ':debug';
in order to get that behavior. The debug option doesn't change how the
script behaves in a CGI environment. I have no clue why this change was
made -- imho, it's rather annoying.

Subject: delete directory files from a list. Help Please
Message-Id: <YW50aWdvbmU=.ed819e6f4d9b2320e91bb3828d498735@1059104300.cotse.net>
Here is my problem. I want to delete the files contained in a directory
from a list contained in a file. Here is an example:
The input file is a regular text file in the following format (call it
myfile.txt);
item1
item2
item3
item4
...
What I want to do is look in a directory and delete any file in the
directory that contains any item on the list. For example, lets say the
contents of the directory looks like this:
07/24/2003 01:27 AM 3,812 heresanitem1
07/24/2003 10:42 PM 912,126 heretoitem2
07/14/2003 12:19 AM 234 item3ishere
06/12/2003 10:25 PM 34,049 leavemealone
06/12/2003 10:25 PM 16,683 leavemealonetoo
07/22/2003 11:36 PM 1,825 yupitem4yup
...
I would like to read each line of the file from "myfile.txt" [getline() I
suppose] and then delete the files that have ANY MATCHING information from
the input file. So if the input file has "item1" it will delete the file
"heresanitem1" as well as "alsoitem1aswell" from the directory. So when I
run the script the sample directory above will look like this:
06/12/2003 10:25 PM 34,049 leavemealone
06/12/2003 10:25 PM 16,683 leavemealonetoo
...
This problem has been tough for me. I have read everything I can get my
hands on concerning unlink but I cannot get this problem solved. Any help
appreciated.

Sounds like s/he's actually trying to parse the httpd configuration
files. There is probably a module to do that, check CPAN.

May I humbly suggest not doing any actual deleting programmatically until
you're sure that your program works as expected _and_ you've fed it
unexpected input. The first few times you test, rather print the cammands
that would have been executed so that you can make sure it is not doing
anything unexpected.
Also, don't run this script with too liberal permissions. If you unlink
things as root for instance, you're tangoing with disaster.

Well, the problem description does mention the information being in a web
page generated using ASP, and part of the objective seems to be to
extract the list of 'active' vhosts from that page.

Modules are your friend. You may
use LWP::Simple;
to get() your web page. It is very simple:
use LWP::Simple;
use warnings;
use strict;
my $webpage=get('http://some.server.com/some/path...');
Then you'll need to parse the HTML to retrieve the info you want:
use HTML::Parser;
might help with that. Warning: Parsing HTML is much harder than it
looks at first glance -- that's why HTML::Parser is there. Good luck.

I found the answer after having posted the question. You use g++ instead of
gcc for linking (as directed in makefile.mk). Your advice will still be
used (at least it's worth printing out). Thank you.

I don't know of any with that duration.
You might try the "Continuing Education" department of colleges
near where you live.
There is also a list of Perl training organizations at:

Stonehenge offers classes suitable for that audience.

Stonehenge's classes are generally 4 days, 7 contact-hours per day,
split about 60/40 lecture/lab. Computers are provided.

The cost for a 4-day Stonehenge open-enrollment class is about $1600.
So for about $3200 you could have both the "Learning Perl" and
"Learning Perl Objects, References & Modules" courses, which are
the basis of the O'Reilly books of the same names.
Contact me if you'd like more info.

Maybe it would be a good idea to append that URL to the bottom of

I'll do better than that. I tell you how you can locate lots of things.
There are "search engines" that can locate things on the web.
A popular search engine is www.google.com.
Entering
perl posting guidelines
in the little box there will find them.
Or, read the newsgroup regularly, they are posted twice each week.

If your program/module uses modules not within the core distribution,
is it acceptable practice to package with it a copy of that module?
Particularly in the case of XS extensions. Is an XS module built on
one system the same as any another? Or should I just inform the user
which modules they must install?

It's easiest if you just tell the users which modules they need to
install. That way they can do it in the way they are used to doing
it[1]. This also allows people to keep the module that you rely on up
to date, independently of your distribution. Since they need to
install your module anyway, they should already know how to do that.
The next best alternative is to include a copy of the original tar
file of the distribution you want added, _if_ the license of that
module allows you to do that.
It is not a good idea to roll the source files of that module into
your own package, because you just enter maintenance hell. You would
also need to come up with some mechanism to avoid installing your
copies of that module if a valid copy already exists on the system.
This is much more trouble than it ever can be worth.
Distributing binaries is only going to be successful if you can
precompile and package the module for each version of each OS and each
version of each Perl you are going to need it for. Binaries are
generally not compatible between OSes, and often not compatible
between various versions of Perl.

[1] not everyone maintains their Perl installation by compiling and
installing stuff themselves by hand, or via the CPAN module. there's
Activestate distributions and their ppm tools. There are Linux
distributions that pre-package perl modules. Pre-compiled Solaris
packages are available for Perl modules.

No.
Compiling C depends on the libraries that the compiler uses.
Different systems may have different libraries.

No. The pure perl parts are (obviously) the same, but the compiled binaries
will be different. For those users who have the same OS as you, you could do
as you're suggesting. (Or you could even provide separate binaries for a
range of operating systems, as ActiveState do in regard to their ppm
packages.)
Also be aware that 5.6 and 5.8 require different binaries.
Or should I just inform the user

This is the more usual way, which you'd normally do by specifying
'PREREQ_PM' in the WriteMakefile() section of your module's Makefile.PL. (A
good idea to mention it in the readme, too.)
Cheers,
Rob

I read Martien's reply to your question, and it appeared to be good
advise. But only sometimes. I'd say it depends on which kind of
program it is, and the target audience for it.
I have a CGI program, where I include a few non-core (not XS
extensions, though) modules from CPAN. The users of my program are
typically on shared web accounts, most often without shell access.
Accordingly, they simply upload the modules via FTP to a program
specific Perl library.
The program includes a
use lib 'lib';
command, which makes the program specific path the first path in @INC,
and accordingly 'my' distributed copies are always loaded whether they
were already installed as a part of the Perl installation or not. (But
not when running other programs, of course.)
To be honest, I can't think of doing it in any other way.
Now, would the just described method be bad practice? Personally I
can't see why.

Subject: Problems compiling perl 5.8 on Solaris with GNU ld
Message-Id: <e09c438a.0307241932.6cbe49b0@posting.google.com>
Hello there,
I had problems when compiling perl with GNU ld (binutils package).
Therefore I had to compile perl using the utilities that came with sun
(/usr/ccs/bin). The make always failed with an error like miniperl
something and complained about floor, socket etc being unreferenced.
Is there something I could have done to compile perl with GNU ld
successfully ?
Regards,
VS

You should always, yes *always*, check the return value from open():
open (INFILE, 'db1.dat') or die "could not open 'db1.dat' $!";

I don't see how the code above can produce the output you claim.
Do you have a short and complete program that we can run that
illustrates the problem you are having?
If you can do that, then we can surely answer your question...

Um, no you don't.

Maybe one of the other guys has a better solution, but I'd be looking at
map right now if I were you.

UTF-8 support is native in Perl 5.8. See:
