I'm trying to refactor an application I wrote a few months ago and ran
into a question about SIG{TERM}.
Currently I have a single application that uses the approach of:
my $please_die = 0;
$SIG{TERM} = sub {$please_die = 1 };
to control when I should exit out of different loops and structures.
Hi,
I have tried the following script:
use threads;
my $threads = async {foreach(1 .. 70) {download($_)}};
$threads->join();
$threads->detach();
sub download {...}
This program takes the same amount of time to run like when not using
threads, but a simple for() loop.
How can I make it to run a

This creates a single thread to execute the block. The choice between

I'm not too familiar with threads, but I'll give it a go. You're still
executing the download() sub seventy times one after another rather than
concurrently. The async function will created one new thread for the block

Retrieve, delete what's left, and rewrite what's to be kept. It should now
work everytime all the time. C

No. With alias, I can create an alias file that works with sh (and ksh,

With all the debate going on, let me just say that a perl script was THE
ONLY method that allowed me to change paths in 13,161 files and scripts when
I moved from one provider to another. Try a *one-liner" on multiple files
(13,000+) located in different directories...

Hi,
I have Hash of array. I want to compare the array values within the hash.

You need to dereference the array at $var{$key} in a similar way to the
way you did it when you created the array, so something like this should
work:
foreach my $key(keys %VAR){
foreach my $element(@{$VAR{$key}}){
#do something...
}
