Re: Delete specific lines from txt file.

Alternatively structure/dump the file as a hash (example below), forget all about duplicated blank lines and extra spaces and delete the hash-key provided as argument to the script. You could have a lot of troubles if some lines are duplicated, new fields are added later for new registers, or some fields are missing and you simply delete five untested lines here and there.

my %sports= (
    'johnlazybones' => {
        'firstname' => 'John',
        'lastname' => 'lazybones',
        'sport' => 'none known, never, ever', 
         }, 
     
   'michaelflops' => {
        'firstname' => 'Michael',
        'lastname' => 'flops',
        'sport' => 'sillonball', 
        'victories' => {
            '1' => '01-AUG-2012',
            '2' => '12-SEP-2011',
        },
    },
);
