removing emty lines without creating a new file or array

[Konrad Foerstner]

Hi,

My problem today ;) : I have a file with some unmeant empty lines and I
want to remove them, without writing a new file and without storing all
the content temporarily in an array. I thought about the following lines
of code, but they don't do the job.


open (FH, "+<$filename");

foreach (<FH>){
    $_ =~ s/^\n//g;
}


What's wrong?

Konrad
