How about this?

#!/usr/local/bin/perl -w use strict; use Data::Dumper; my %old_hash = ( '1.1.1.1' => 'nfs,1', '4.4.4.4' => 'cifs,0', '10.0.4.2' => 'afp,1', '3.3.3.3' => 'nfs,0', '5.5.5.5' => 'afp,0', ); my %new_hash = ( '1.1.1.1' => 'nfs,0', # index change '200.4.4.4' => 'cifs,0', # IP change '200.0.4.2' => 'afp,1', # IP change '3.3.3.3' => 'nfs,1', # index change '5.5.5.5' => 'afp,0', '4.22.2.22' => 'afp,2', # new entry ); my %changes; foreach my $key ( keys %new_hash ) { $changes{$key} = $new_hash{$key} unless ( (exists $old_hash{$key}) && $new_hash{$key} eq $old_h +ash{$key} ); # gotta check for existence to quiet warnings. } print Dumper( \%changes );
Outputs:
:!./test.pl $VAR1 = { '4.22.2.22' => 'afp,2', '1.1.1.1' => 'nfs,0', '3.3.3.3' => 'nfs,1', '200.4.4.4' => 'cifs,0', '200.0.4.2' => 'afp,1' };
Let me know if you see anything that it would miss.

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.
