in reply to match multi-lines from config file

Use open to open a file handle then use:

while (<IN>) {

[download]

to scan the file. Use index or a regular expression match to skip (using next) until the interface line is found. Skip until the description line is found:

/^description/ && last while <IN>;

my $description = $_;

[download]

Process the description then use the same technique for the rest of the lines you need to match.

    /^description/ && last while <IN>;
    that confused the heck out of me! how about this form? 
        $_ = <IN> until /^description/;

    [download]
     doh!

[d/l]
[select]

      Because that tests $_ before the first value is assigned to it and doesn't terminate for a file that doesn't include a matching line!
