This could be entered into a hash fairly simply. First set the filehandle to read in paragraph mode, (local $/ = ''), within a limited scope (determined by the enclosing braces, {  }). Then a simple split /\n/ will capture the key and the values in an array.

EDIT: added for loop that removes quotes from beginning and end of items in @data

Usage: perl my_program.pl input_file

#!/usr/bin/perl use strict; use warnings; use Data::Dumper; my %data; { local $/ = ''; while (<>) { my ($key, @data) = split /\n/; for (@data) { s/^"//; s/"$//; } $data{$key} = \@data; } } $Data::Dumper::Indent=1; print Dumper \%data;
Prints:
$VAR1 = { 'arn:aws:iam::12345678901:role/Role2-Role2' => [ 'Alexa for Business', 'AWS Certificate Manager', 'AWS Certificate Manager Private Certificate Authority', 'AWS Amplify', 'Manage - Amazon API Gateway', 'Application Auto Scaling', 'AWS App Mesh', 'Amazon AppStream 2.0', 'AWS AppSync' ], 'arn:aws:iam::11111111111:role/ADFS-MyRoleName' => [ 'Alexa for Business', 'AWS Certificate Manager', 'AWS Certificate Manager Private Certificate Authority', 'AWS Amplify', 'Manage - Amazon API Gateway', 'AWS App Mesh', 'Amazon AppStream 2.0', 'AWS AppSync', 'Amazon Athena', 'AWS Auto Scaling' ] };
(The output is a little messy due to the long key names.)

EDIT: Used Indent to Data::Dumper to clean up output from Dumper as noted by jdporter

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
