Question

Suppose I have a file with these inputs:

line 1


line 2

line3

My program should only store “line1”, “line2” and “line3” not the newlines. How do I achieve that?
My program already removed leading and trailing whitespaces but it doesn’t help to remove newline.
I am setting $/ as \n because each input is separated by a \n.

Answer 1

while (<>) {
    chomp;
    next unless /\S/;
    print "$_\n";
}
