Re^2: Storing the log file name as key/value in hash

    Thank you. Sorry, i didn't get how this has to be compared to my array

     /^(.+?)\.(.+?)\.IP/ and push $hash1{$2}->@*, $1 for @array;

    This gives me Syntax error.

      Try this, or use a more recent version of Perl.

      /^(.+?)\.(.+?)\.IP/ and push @{$hash1{$2}}, $1 for @array;

        Thank you so much. One last thing please need to write the output to a file as

        keyValue : <comma separted values>

        Thanks once again for your time.

      This is an older syntax style that does the same 

      /^(.+?)\.(.+?)\.IP/ and push @{$hash1{$2}}, $1 for @array;

        Thank you so much. One last thing please need to write the output to a file as

        keyValue : <comma separted values>

        possibly file name with each key and value Thanks once again for your time.
