I have a script problem that I am not able to solve due my very limited understanding of unix/awk.
This is the contents of test.sh
awk '{print $1}'
From the prompt if I enter:
./test.sh Hello World
I would expect to see "Hello" but all I get is a blank line. Only then if I enter "Hello... (2 Replies)

padre::task::ppi
Padre::Task::PPI(3pm) User Contributed Perl Documentation Padre::Task::PPI(3pm)NAME
Padre::Task::PPI - Generic PPI background processing task
SYNOPSIS
package Padre::Task::MyFancyTest;
use strict;
use base 'Padre::Task::PPI';
# Will be called after ppi-parsing:
sub process {
my $self = shift;
my $ppi = shift or return;
my $result = ...expensive_calculation_using_ppi...
$self->{result} = $result;
return;
}
1;
# elsewhere:
Padre::Task::MyFancyTest->new(
text => 'parse-this!',
)->schedule;
DESCRIPTION
This is a base class for all tasks that need to do expensive calculations using PPI. The class will setup a PPI::Document object from a
given piece of code and then call the "process_ppi" method on the task object and pass the PPI::Document as first argument.
You can either let "Padre::Task::PPI" fetch the Perl code for parsing from the current document or specify it as the ""text"" parameter to
the constructor.
Note: If you don't supply the document text and there is no currently open document to fetch it from, "new()" will simply return the empty
list instead of a "Padre::Task::PPI" object.
SEE ALSO
This class inherits from "Padre::Task" and its instances can be scheduled using "Padre::TaskManager".
The transfer of the objects to and from the worker threads is implemented with Storable.
