I've found it handy to be able to neatly encapsulate sh/bash shell scripts in here documents passed to system() as follows:

#! /usr/bin/perl

sub whatever
{
    system <<'SCRIPT';
date
echo "what about this?"
SCRIPT
}

whatever;

However, I've not been able to find a syntax that allows passing arguments to the shell script in the here document. I've been able to sort of work around it by passing environment variables like this:

#! /usr/bin/perl

my $value = "testvalue";

sub whatever
{
    system "MYVAR=$value;" . <<'SCRIPT';
date
echo "arg1($MYVAR)"
echo "what about this?"
SCRIPT
}

whatever;
[download]

But that's unsatisfying. What I really want is to pass positional arguments to the scripts, and reference them via the likes of $* or $1 within the embedded shell script As Usual.

The following ALMOST works (nods to Murphy's Law), except for the fact that the first argument winds up in $0 instead $1..... ugh....

#! /usr/bin/perl

my $rc = system ("sh", "-c", <<'SCRIPT', "one", "two", "three");
echo 'this is a test'
echo 'again'
echo "0($0) 1($1) 2($2)"
SCRIPT

$rc >> 8;

exit $rc;

<LATER STILL...>

Um, DUH! The above technique works fine if a pass a dummy program name argument first.....

#! /usr/bin/perl

my $rc = system ("sh", "-c", <<'SCRIPT', "bogus_program_name", "one", 
+"two", "three");
echo 'this is a test'
echo 'again'
echo "0($0) 1($1) 2($2) 3($3)"
SCRIPT

$rc >> 8;

exit $rc;
