I want to skip the blank lines and just print the lines with text, like this
When you say "blank", do you mean lines with NO characters at all (other
than the ending newline) or lines that ONLY contain whitespace?
chomp;
next if ($_ =~ /^\s+/);
Ok, if the line is ONLY "\n", then if you chomp() it, the line will be the
empty string, "". This means it WON'T be matched by /^\s+/.
Your regex doesn't make any sense to me. It would skip lines that start
with a space, like " This one". And what's the use of looking for more
than one leading space?
I have a couple possible solutions for you. If you want to skip lines
that consist of ABSOLUTELY NOTHING other than a newline, then you can do:
while (<FH>) {
chomp;
next if $_ eq "";
...
}
If you want to skip lines that only have whitespace characters, then you
can do:
while (<FH>) {
chomp;
next unless /\S/;
}
