As a side note, when I was the lead guy during the once famous "Langley Cyber Attack", where my work in an epic "email reply spam battle" happened over two decades ago, long before spam filters became of age, we wrote all our email anti-spam filters and detection algorithms in PERL.
Edit: For anyone interested in the early days of "cyberwar" in the 1998/1997 timeframe:
That PERL code "way back when" was "very crude" by todays standards, but it was very effective and fast. PERL was the best tool for that job "way back when". I was a huge PERL advocate back then, and would write all scripts in PERL, even when PERL was not needed. I loved PERL so much back then that I tried to get everyone to learn it and use it.
Sometimes old guys like me forget that the younger generations may not have had the chance to develop code in PERL and other "out of favor" programming languages these days. But when I read this discussion it brings back wonderful memories of some of the best "tech days" of my life, defending the US Air Force against hackers with PERL scripts in real-time.
wisecracker, I say "go for it" if you or anyone reading this has the time or interest to learn PERL. I would love to see a lot of people posting PERL problems here. Perhaps that would jog even more great memories from decades ago from the deep trenches of cyber warfare battles when the web was but an infant.
Can anyone tell me if the copy command in PERL has the same functionality as in KSH shell in UNIX or does it actually move the file ??
$cp_stat=system("cp $ENV{OLAMEBSDIR}/data/olam.ddabal$type $ENV{OLAMDIR}/balance/data/olam.ddabal$type.$HeaderDate"); (1 Reply)

When i run my perl/tk script, a perl window pops up behind the GUI window,, can this be hidden????
Also, can the Icon be changed, the Tk icon in every window??? (1 Reply)
If I use 2 system commands in a script, will one finish before the next one starts? or will it start the first and the second at the same time?
i.e.
system("ps | grep rminer");
system("ls -al | grep 431"); (1 Reply)
Hi everyone
I am not even a novice at Perl scripting .. but had to edit one the other day. The only way I can get it to run is by prefixing 'perl' before running it - ie # perl scriptname
I am running AIX.
Any ideas why i have to do that ?
Thanks! (2 Replies)
Playing with an until loop as follows:
my $input;
until ($input eq "quit") {
print "Please enter something:";
$input = <STDIN>;
chomp $input;
if ($input eq "dog") {
print "cat" ;
}
else {
print "Please re-enter";
}
}
Something simple like this...

I am new to Perl and got a real stupid question. We are trying to install the Date:Calc package for some calculations with dates.The security guys mentioned they won't install it as root in /usr/bin/perl but have asked us to install it in any directory and use it from there.

yaml::xs
YAML::XS(3pm) User Contributed Perl Documentation YAML::XS(3pm)NAME
YAML::XS - Perl YAML Serialization using XS and libyaml
SYNOPSIS
use YAML::XS;
my $yaml = Dump [ 1..4 ];
my $array = Load $yaml;
DESCRIPTION
Kirill Siminov's "libyaml" is arguably the best YAML implementation. The C library is written precisely to the YAML 1.1 specification. It
was originally bound to Python and was later bound to Ruby.
This module is a Perl XS binding to libyaml which offers Perl the best YAML support to date.
This module exports the functions "Dump", "Load", "DumpFile" and "LoadFile". These functions are intended to work exactly like "YAML.pm"'s
corresponding functions.
CONFIGURATION
$YAML::XS::UseCode
$YAML::XS::DumpCode
$YAML::XS::LoadCode
If enabled supports deparsing and evaling of code blocks.
$YAML::XS::QuoteNumericStrings
When true (the default) strings that look like numbers but have not been numified will be quoted when dumping.
This ensures leading that things like leading zeros and other formatting are preserved.
USING YAML ::XS WITH UNICODE
Handling unicode properly in Perl can be a pain. YAML::XS only deals with streams of utf8 octets. Just remember this:
$perl = Load($utf8_octets);
$utf8_octets = Dump($perl);
There are many, many places where things can go wrong with unicode. If you are having problems, use Devel::Peek on all the possible data
points.
