[ That "Last-modified:" date above refers to this document, not to the
Perl FAQ itself! The last _major_ update of the Perl FAQ was in Summer
of 1998; of course, ongoing updates are made as needed. ]
For most people, this URL should be all you need in order to find Perl's
Frequently Asked Questions (and answers).
http://www.cpan.org/doc/FAQs/
Please look over (but never overlook!) the FAQ and related docs before
posting anything to the comp.lang.perl.* family of newsgroups.
For an alternative way to get answers, check out the Perlfaq website.
http://www.perlfaq.com/
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
Beginning with Perl version 5.004, the Perl distribution itself includes
the Perl FAQ. If everything is pro-Perl-y installed on your system, the
FAQ will be stored alongside the rest of Perl's documentation, and one
of these commands (or your local equivalents) should let you read the FAQ.
perldoc perlfaq
man perlfaq
If a recent version of Perl is not properly installed on your system,
you should ask your system administrator or local expert to help. If you
find that a recent Perl distribution is lacking the FAQ or other important
documentation, be sure to complain to that distribution's author.
If you have a web connection, the first and foremost source for all things
Perl, including the FAQ, is the Comprehensive Perl Archive Network (CPAN).
CPAN also includes the Perl source code, pre-compiled binaries for many
platforms, and a large collection of freely usable modules, among its
560_986_526 bytes (give or take a little) of super-cool (give or take
a little) Perl resources.

http://www.cpan.org/doc/FAQs/FAQ/html/
http://www.perl.com/CPAN/doc/FAQs/FAQ/html/
You may wish or need to access CPAN via anonymous FTP. (Within CPAN,
you will find the FAQ in the /doc/FAQs/FAQ directory. If none of these
selected FTP sites is especially good for you, a full list of CPAN sites
is in the SITES file within CPAN.)

If you have no connection to the Internet at all (so sad!) you may wish
to purchase one of the commercial Perl distributions on CD-Rom or other

Hi,
I was wondering if anyone has been successfully installed Perl
DBI and DBD::ODBC in Windows 95 platform. I tried to but it
gave me a "fatal error" after I used 'nmake'. Where can I download
'dmake' or the latest version of 'nmake'? Should I use 'ppm' instead?
If I should then how (the Perl documentation doesn't seem to help)?
Thanks a lot in advance.

Subject: beginner problem
Message-Id: <8mrj38$uel$1@netnews.upenn.edu>
Just started learning perl. I have already read through the faq,
etc...but I am working with a book Elements of Programming with Perl by
Johnson. In an early chapter he give a program to search through the faq
files for help. I followed and copied it, but when I have a problem when
it runs.
##faqgrep.txt##
use strict;
my $faq_directory = 'C:\perl\html\lib\pod';
my @faq_files = ( ##various files like 'perlfaq1.pod'##);
my $pattern = SARGV[0] or die "no pattern available: $!";
foreach my $filename (@faqfiles) {
open (FILE, "$faq_directory\$filename) or die "cant open file: $!";
#####
This is most of the code but the problem is when I run the program I get
the error "cant find perlfaq1.pod in C:\perl\bin\faqgrep.txt"
...this is how I run the above program (C:\ perl C:\perl\bin\faqgrep.txt)
but I clearly identified the $faq_directory as 'C:\perl\html\lib\pod' but
for some reason it only wants to look in the directory where I call the
program "faqgrep" from. I have tried a few different syntax changes and
have decided the problem is not with the syntax...so I am at a loss??
I use active perl 5.06 on a windows 98 machine. One thing I have noticed
that doesnt seem right is that according to the book I should be able to
run perl programs (.txt files) by simply C:\ perl "program name"...but I
have to first C:\path C:\perl\bin then C:\ perl
C:\perl\bin\"filename.txt" ( I keep my files in the \bin folder.
Perhaps I have set up something incorrectly, cause it seems that the only
way for this program to find the 'perlfaq.pod' files is if I relocate
them to C:\perl\bin\faqgrep.txt ..which isnt possible?
why is perl insist on looking in the wrong folder?

And why would you attempt to run DOS on a Unix machine? (Not
that it can't be done) Don't you mean a command line program? The Unix
command line is infinately better than DOS.

Yes: the maintained HTML documentation, and the HTML-ified POD
documentation derived from the module source. See these words of a
reply from the author:
After receiving this e-mail I went and checked the CGI.pm docs, and
sure enough there is an obsolete reference to the URI: header in the
POD but not HTML documentation. Since the code doesn't do what the
POD documentation says it does, I have removed the incorrect
reference. The PerlFAQ should be updated as well.
from which it seems obvious that the "HTML documentation" and the POD
are not the same thing. See also
<Pine.GHP.4.21.0007041142530.5516-100000@hpplus03.cern.ch>
If we take for example 2.69, the HTML documentation, cgi_docs.html in
the top level subdirectory, has this near the beginning:
<H2>Abstract</H2> This perl 5 library uses objects to create Web
fill-out forms on the fly and to parse their contents. It provides a
simple interface for parsing and interpreting query strings passed to
CGI scripts. However, it also offers a rich set of functions for
creating fill-out forms. Instead of remembering the syntax for HTML
form elements, you just make a series of perl function calls. An
important fringe benefit of this is that the value of the previous
query is used to initialize the form, so that the state of the form is
preserved from invocation to invocation.
[and, shortly afterwards]
A script to create a fill-out form that remembers its state each time
it's invoked is very easy to write with CGI.pm:
#!/usr/local/bin/perl
use CGI qw(:standard);
, which you won't find in that form in the POD.
Whereas the POD begins:
=head1 SYNOPSIS
# CGI script that creates a fill-out form
# and echoes back its values.
use CGI qw/:standard/;
print header,
start_html('A Simple Example'),
, which you won't find in that form in the HTML documentation.
Throughout the POD you'll find differences in detail from the
supported HTML documentation, just as Lincoln Stein's comment
indicates, and as I reported in my previous postings.
The HTML documentation that's automatically installed with ActivePerl
is clearly an HTML-ified version of the POD, and _not_ the supported
HTML documentation itself.
The standard Perl distribution also comes with a procedure for
creating HTML-ified PODs, including the modules that are incorporated
in Perl as standard. It doesn't seem to include the "proper" CGI HTML
documentation at all. So, again, users of Perl who have not
explicitly installed CGI.pm are apparently getting "sold short" with
the POD documentation instead of the real, author-supported, HTML
documentation.

No one told you that. You made a statement that mathematicians do not
use commas as decimal points, which is a general statement and is
incorrect if you're not talking only about electronic devices, such as
computers and calculators.

*8^) .. "ad absurdum" .. should I be insulted instead of amused ? .. I
think you might have missed my point
I wasn't trying to wash anything away Larry .. I said - "I believe that
it's a simple case of - you've gotta draw the line somewhere"
the point I was making .. was that with
print "if(1) { print 'abc'; }";
you obviously don't want Perl to evaluate the code .. so .. somewhere
between the above and
print "blah $x->func() blah";
there's a line .. so you want the line drawn somewhere between the two
someone else obviously wanted the line drawn (more obviously if you ask
me) at between variable interpolation and ANY code evaluation that
wasn't directly required to interpolate a variable

I agree .. it's an arbitrary decision .. point is that the line has to
be drawn somewhere
I think most would agree that you don't want to have to think about all
Perl keywords in a double-quoted string .. so no one (or few at least)
would want
print "print while true";
to loop forever printing $_ .. so - the line has to be drawn somewhere
on _this_ side of allowing that .. do you allow named self-defined
function calls ?
print "this is the output from \myFunc() myFunc()";
probably not .. so do you only want to provide dereferenced function
calls ?
print "$myfunc->('x')";
I think that a more obvious spot to drawn the line (it's certainly
easier to explain to a beginner) is between variable interpolation and
code evaluation .. I guess I should throw it back at you .. why bother
increasing the scope of double-quoted string evaluation ? .. already
there are tricks to have what you want .. so why change the language
when there's currently a clear distinction - that of variable
interpolation vs code evaluation ?

That is indeed one possible convention. You seem to have hung too
much onto it though.
The use of filename extensions to denote the nature of the file
content is itself only _by convention_. Some OSes have other
mechanisms for doing that, like content-type fields in a file

Subject: Downloadable 5.6 documentation in HTML
Message-Id: <8mrj3s$il4$1@nnrp1.deja.com>
As far as I can see from checking both www.cpan.org and www.perl.com,
the downloadable HTML documentation appears to refer to older releases
of Perl than 5.6 (e.g it has perldeltas for two older releases but
nothing for more recent ones).
Is this the most current documentation for 5.6 (which I would
presumably then supplement with added files), or is there a more up-to-
date copy of the documentation in HTML format available somewhere?.
Incidentally I have only recently upgraded to 5.6. There are anecdotal
reports in this group that 5.6 is 'buggy'. But given the historically
very high quality of Perl releases, does anyone feel that 5.6 is
significantly less reliable than, say 5.005_03?. I would much prefer to
use it because if nothing else, if there are problems, then these need
to be 'smoked out' by as large a user base as possible, and then
reported back.

NT includes rsh (%systemroot%\system32\rsh.exe). Create a user on
your solaris box with restricted rights and a .rhosts file containing
your
IIA host/IIS user (not writable by your user). Then wrap the supplied
unix commands into $output = qx{ rsh <host> -l <user> $cmd}; and put
the output in the HTML page to be send to the browser.

You can use Perl2exe to convert your code to binary form for
multiple OS', however, you'll never be able to run it persistently
after that. Somehow I don't think that will be a problem though.

Subject: Extracting string between XML tag pair from file
Message-Id: <39910E44.28BDAFF1@eurodyn.com>
Hello,
I've got a huge file so I've need to extract a string which matches
between first occurance of XML pair of tags.
So, for example I've need to extract all between first apperiance of
<EMPLOYEE> and first apperiance of </EMPLOYEE> in a file, including
<EMPLOYEE> and </EMPLOYEE> as part of string.
Inside file could be much more <EMPLOYEE>...</EMPLOYEE> tags, but I've
need between the first ones.
Regargs,
Sasa

Have a look at XML::Parser (from CPAN).

Subject: files transferred by socket?
Message-Id: <8mrbk4$7sn@netnews.hinet.net>
I tried to send files from socket by this way
server:
open(FILE,$file) or die "error";
binmode(FILE);
while(<FILE>){
print $sock $_;
}
close FILE;
client:
open(NEWFILE,">newfile");
while(defined ($_=<$sock>)){
print NEWFILE $_;
}
close (NEWFILE);
the data that client receive is always larger than the original one.why?
I tried both text and binary file and the result is the same.
If I comment the binmode then it works for text file but not binary.
Is there a general way for both types of files?
The problem is encountered on windows platform and O.K. for linux.
does this problem result from the platform issue?
Thanks for help.

Subject: Generated or received a file descriptor number that is not valid
Message-Id: <8mr1a1$jk4$1@news.netmar.com>
i,
I have a couple of small perl scripts...
One is exec.pl ...
#!/usr/local/bin/perl -w
my $CmdStr1 = "my.pl > lst1";
my $CmdStr2 = "my.pl >& lst2";
system ("$CmdStr1");
system ("$CmdStr2");
.. and other my.pl ...
#!/usr/local/bin/perl -w
print "An STDOUT String1\n";
print STDERR "An STDERR String2\n";
print "An STDOUT String3\n";
print STDERR "An STDERR String4\n";
Upon executing exec.pl, these are the responses that I get on two
versions of perl (on two different OSs).
On perl version 5.005_03 built for i386-linux, (Exactly the way I want)
An STDERR String2
An STDERR String4
(Lst1 has only the STDOUT messages & Lst2 has both STDERR & STDOUT
messages)
And on perl v5.6.0 built for 9000/777-hpux, (Error. Functionality, not
as desired)
An STDERR String2
An STDERR String4
sh: lst2: Generated or received a file descriptor number that is not
valid.
(Lst1 has only the STDOUT messages. Script exits before generating Lst2
due to an error)
------------------------------------------------------------------------
I think the problem lies in the '&' in $CmdStr2. If that is removed,
all's well - except the functionality - because I want all the STDERR
& STDOUT messages to go into the lst files. Is there any way I can get
response on v5.6.0 similar to the 5.005_03?
I have an idea that perl 5.6.0 treats file descriptors differently as
compared to its predecessors - as real variables. But I am not sure if
this problem is related to that fact.

This one-liner does it:
perl -pi -e s/X/Y/g file1 file2 ... fileN
The rest is literature...

Not much to write. Using the -i.bak command line option, you can modify
any line you like in the script. With the -p option, you don't even need
the "while(<>){ ... }" and the "print".
Script:
s/foo/bar/;
Gee that's big. Command line:
perl -pi.bak myscript.pl myfile.txt
