Currently I own a 'learning perl' 3rd edition and I noticed that 5th
version is coming out in june.
What I didn't realize was that learning perl 4th edition's been out
since 2005.
I was going to order 5th version in june but does anyone in here know
the different between 3rd and 4th version?

Hi guys again!
I am sure this questions been around for while but I am not sure where
to begin.
I am trying to grep a html page given a URL and then extract some
information from the source code.
So something like
open FH, www.example.com/index.html | , or die no way : $!\n;
@array = FH;
I am running this command on over 2 gigs worth of lines
which one should be faster?
cut -d'|' -f21 * | sort | uniq -c | sort
perl -F\| -lane 'print $F[21]' * | sort | uniq -c | sort
or is there faster ways to do this on perl?

Richard Lee:
[$file1,$file2,$file3,$file4,$file5,$file6,$file10,$file25]
I didn't want to put them in array
since I need to use individual named variable later
And why is that?
Maybe because in the real code

But better stop guessing and let Richard answer.
yes, variables are particular names and later I wanted to refer back
by variable names.
However, for now I have done this so far so I just added as array
instead of breaking out

I just looked it up on perldoc perlvar, but I am still not sure what it
does.
$^I The current value of the inplace-edit extension. Use undef
to disable inplace editing. (Mnemonic: value of -i

I was reading perl cookbook and saw this example, and was wondering

I use this before (split slice ) but it's working bit funny now..
can someone tell me why??
it looks like it's splitting on '' instead of /|/ as I have specified
below... ??
use strict;
use warnings;
my $array = q/hi|how|are|you|fine/;
my ($moe,$hae,$now) = (split(/|/,$array))[0,1,2];
I dont know how to go through the array over and over again pending on
my previous search so I ended up writing it like below which works.. but
looks really really
inefficient..

my $routename = shift;
my $routegroupid;
