Use one-liner Perl to do the replacement without calling 'open' and
'<>' and 'close' directly.

Hi,
Rather than a dynamic array,you just need to use a correct datastru,a hash.
It's maybe better to write codes as below.

I have a 'config file' that contains a group name (alphanumeric) and

Thank you Chas! I checked that out and found their tutorial which
