Deleting line spacing

Is there a code to delete the line spaces between sentences or words in a file?
I mean when i've word like this:

-> Input.txt



1.The file you are looking for might have been moved.


2.If you typed the address in the navigation bar.

i.e. maybe with 2-3 line spacing,and i need to remove the line spaces to:

-> Output.txt

    Two methods:-

    1) If the file is reasonably small, read the file into an array, so there is one line per element, then grep for non-empty lines.

    @lines = grep { $_ ne "
    " } @lines;

    2) If it's a bigger file, loop through it.

    [code]open IFILE, "< input.txt";
    open OFILE, "> output.txt";
    while () {
    print OFILE $_ unless $_ eq "
    ";
    }
    close IFILE;
    close OFILE;[/code]
