passing a hash to another script in perl

First I'd like to remind you if possible to use some other alternative methods to achieve your goal (eg. combining the 2 scripts into one), as it seems the method you mentioned is a little complicated.
But if you persist, read the followings. Basically, you need some kinds of IPC (inter process communication) methods to transfer the hash data. there are a lot of options. steps, 1. create pipes in the script1.sh before calling script2.sh. 2. calling script2.sh 3. script1.sh write the hash data to the pipe, you can use whatever for format you like, I recommend using Data:
umper(). 4. script2.sh reads the data coming from script1.sh, via the pipe 5. convert the data you received to the object in perl. This is simple if using Data:umper(), just eval ().

template::plugin::dumper
Template::Plugin::Dumper(3) User Contributed Perl Documentation Template::Plugin::Dumper(3) NAME
Template::Plugin::Dumper - Plugin interface to Data::Dumper SYNOPSIS
[% USE Dumper %] [% Dumper.dump(variable) %] [% Dumper.dump_html(variable) %] DESCRIPTION
This is a very simple Template Toolkit Plugin Interface to the Data::Dumper module. A "Dumper" object will be instantiated via the following directive: [% USE Dumper %] As a standard plugin, you can also specify its name in lower case: [% USE dumper %] The "Data::Dumper" "Pad", "Indent" and "Varname" options are supported as constructor arguments to affect the output generated. See Data::Dumper for further details. [% USE dumper(Indent=0, Pad="<br>") %] These options can also be specified in lower case. [% USE dumper(indent=0, pad="<br>") %] METHODS
There are two methods supported by the "Dumper" object. Each will output into the template the contents of the variables passed to the object method. dump() Generates a raw text dump of the data structure(s) passed [% USE Dumper %] [% Dumper.dump(myvar) %] [% Dumper.dump(myvar, yourvar) %] dump_html() Generates a dump of the data structures, as per dump(), but with the characters <, > and & converted to their equivalent HTML entities and newlines converted to <br>. [% USE Dumper %] [% Dumper.dump_html(myvar) %] AUTHOR
