I have a file which has several occurances of word1 and word2

Since we're now talking about performance issues, somebody should say something about
precompiling the regular expression, when you can, with either /o or qr(). I had a
process's running time go from 2min 45sec to just under 24sec simply by using qr on
the relevant regular expressions.

Hi all,
I'm parsing a logfile and don't quite understand the behaviour of m//.
From a previous regex match I have already captured $+{'GFP'}:
use strict;
use warnings;

$text =~ m/ (?FILTERS .*? WRT)/x;# I simply have my whole
logfile in $text - I know there are better solutions.

/(?<=Retrieval command for )http:.*?:/
The "Retrieval" part now is contained in a "Look behind section", which
is to mean it's not going to be stored as part of the match.
I'm not sure what other cases you can get in that log file, but this
solves the problem for that particular line

Hello Florian
First a couple of
built-in variables that relate to regular expressions are modified
by every successful pattern match. It is safer to save values that you
may want to use later in a sperate variable. In particular, your regex
m/(?AVG\s\d)/ matches and, because there is no capture named `GFP`
it sets the correspondi

I know this must be a stupid question but:
let's suppose I am matching for one of multiple matches.
Is it better/faster to split it into several pattern matches or just keep it
one match?

Hi Gurus,
I am new to perl and need some help to learn regex in perl. From the
below line i need to extract following:
Part I
1) $ENVFROM = dapi...@testhost.com
2) $ENVTO1 = te...@etc.com
3) $ENVTO2 = te...@etc.com
4) $ENVTO3 = samt...@abc.com
line=EnvFrom: dapi...@testhost.com, HdrTo: ,
EnvTo:
The last line of this code
foreach $PkgFile( @$PkgList )
{
if( $PkgFile =~m/^\s*$/)
gives this warning message
Use of uninitialized value in pattern match (m//) at packagefile.pm
line 838.
How can I solve this? (I have no idea what the code does...)

Hi All,
I am still a newbie in Perl and it is only with the help of this list that I was
able to construct the following pattern match.

The problem that I have just realized that this string will match the first line

That matches the newline character (\n) globally (/g) and replaces it

are not used and the /s option is not needed because there is no . in
