You should use UNIVERSAL::isa on your reference. See:
perldoc -f ref
and

for additional information.

You may find Scalar::Util::blessed() more useful for that.

Scalar::Util::reftype() is just the thing.
use Scalar::Util qw(reftype);

Why do you want to get the full path to a file that is pointed to from a
reference to a type glob?

What "name" should it use when the FH is not associated with any file?
eg:
open FH, 'ls|' ...
What "name" should it use when there is MORE than one name associated
with the file?
There is not a one-to-one relationship between filehandle and filename,
there may not even _be_ any filename.

I'm just curious of why you think that this would be useful.

Well I'm creating a class where one of the arguments to the
constructor
can either be the path to the file to open, or an open filehandle.
Since more than one object is likely to work with the file I thought
it would be more efficient to have the option of passing the
filehandle
around instead of having each object manually open/close the file.
The reason I need the path is not just to open the file, I need to use
the path to make some modifications to it, then do something with it.
I could make it so the first parameter is either undef or a
filehandle, then they could pass the path in the second argument.
I could offer two ways of creating the object:
method 1:
#this would open the file using $path
$obj = new Obj(undef, $path, 'param3');
method 2:
#this doesn't need to open the file, but it still gets the
#path to the file it's working on from $path supplied in
#the second argument
$obj = new Obj(\*FH, $path, 'param3');
So if the first argument is undefined I'll open the file using the
value
supplied in the second argument, and then I also have the path to the
stuff I need to do with it.
If the file's already opened they can send the filehandle instead of
an undefined
value.

In the context of my object the files will always be text/* type
files. Primarily Html. So the person using the object should only
pass a filehandle that points to an appropriate type of file.
But I get your point that filehandles can point to things that aren't
really files. So I guess because of that it probably wouldn't make
much sense for the language to provide a way to get the file name when
there doesn't necessarily have to be a name associated with it.
I think I should be ok though using the method I described in my last
post.
If you see any flaws in the method I described in my last post, please
let me know.

Subject: File::Find Problems with ntfs compressed folders
Message-Id: <bdqonu$70d$1@slb9.atl.mindspring.net>
My apologies if this has already been posted.... Just point where...
I am using the following script to get file path, filename, and
timestamp. Worked fine until the NT guys started compressing folders.
I can point the script explicitly at a compressed folder and it will
recurse down. Unfortunately it does not seem to "see" compressed
folders by default and then recurse down.
Is there an update to this somewhere??
#!c:\perl\bin\perl -w
# power.pl uses the arc server name and returns the full path and file
name
# along with the timestamp of the file......
use File::Find;
# find \&Getit , 'develop/';
# find \&Getit , 'j:/depts/wspproje/projectd/library/';
# find \&Getit , '\\\HDQ_Doc1/Vol1/depts/wsp projects/project

find \&Getit , '\\\myServer.domain.com/PowerServer/';
sub Getit
{
if ( -f && (@FileStat = stat) )
{
$FileName =$File::Find::name;
$FileTime = $FileStat[9];
$LocalFileTime =localtime($FileTime);

You can't. WNU (Win's Not Unix) doesn't have a mail command, as you

Hmm. You appear to be stuck on page 21 of _Learning Perl, 2nd edition_. Did
you by any chance note (see cover) that LP2e is for UNIX Programming?
Others have told you your problem is not a Perl problem. Please heed their
advice.
Now, let's make your problem a Perl problem. It appears you are using MS
Windows, perhaps XP. If so, you may be using ActiveState Perl or IndigoPerl.
If so, good!
Look at the documentation for the Perl module Mime::Lite. By following the
documentation,
you should be able to easily craft a Perl script that will work on your
Win32 system.
If your curiosity overwhelms you, look inside of Mime::Lite to see how it
sends mail for non-UNIX systems. Hint: Perl module Net::SMTP.
When you have a Perl problem, please read the posting guidelines, help
yourself as much as you can first, and return with a Perl question that's
not already answered in the documentation and other easily searchable
sources.
Cheers.

What if the filename is "results.apl"? It's probably safer to

I have no idea what you're asking, or what you're trying to achieve.
open(FH, "somefile") or die $!;
To read the contents of a file in an array, with each record (by
default each line) in an element:
my @lines = <FH>;
If you want to get rid of the line (record) endings at the same time:
chomp(my @lines = <FH>);
To read the content of a file into a single scalar
my $lines;
{
local $/;
$lines = <FH>;
}
> Kindly Cc asimsuter@hotmail.com in your replies.

Ok.... Now... Where is $hash{$variable} set? Where is $variable set?
If I liberally interpret that code (hard to tell what exactly you're
trying to do), I would probably guess that you're trying to do this:
open(FH, "somefile") or die $!;
my @lines;
while (<FH>)
{
last if /^__END__$/;
push @lines, $_;
}

Howdy - I have three tab-delimited files that represent tables of

I need to do JOIN operation on them with with all three tables.
The easiest solution would be not to import the data into any database.
I tried DBD::CSV driver but it is not able to handle the size of the data.
Is SQLite capable of doing such task?

Approach. Can anybody point me to some examples how to connect to Approach,
(using Win32::OLE or sth else) create and manipulate data?

Indeed -- the easiest solution would be to slurp the entire contents of
these files into memory, putting them in one big hash. Assuming, of
course, that you've got enough memory for this.

Maybe, maybe not. That's not a perl question, though.
Certainly, though, if SQLite is capable of doing it, then the perl
interface to the SQLite database library will be capable of doing it.

You know how to run, but you don't know how to walk?
That's backwards. You should learn the command line _first_
and CGI second...
The name of the language is Perl, not PERL.

No, because it depends on what kind of access your particular
host makes available.
Ask them how you can get access to a command line on their machine.

You do not have a Perl question.
You have a question about WWW stuff.
There are newsgroups about WWW stuff, you will have better luck

Vec is used for constructing bit-vectors, and select takes three bit
vectors and a timeout as arguments.
The vec() stuff is equivilant to the C-level FD_SET macros that operate
on fd_set structs, which can then be passed into the C select() function
If you don't understand a word I just said :) then use the IO::Select
module, and don't worry about it, since it takes care of everything for
you.

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.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.
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.
