Code:
#+BABEL: :cache yes :tangle yes :noweb yes
#+NAME: top_block
#+begin_src perl :tangle "test.pl" :noweb tangle
#!/usr/bin/perl
use strict;
use warnings;
open(my $fh, "<", "test.txt")
or die "cannot open < file name: $!";
<<output-all>>
close($fh);
#+end_src
#+NAME: output-all
#+begin_src perl
while (my $line = <$fh>) {
print $line;
}
#+end_src
Outputs a perl file, where the 1-st line is blank. What should I do to
remove it?

You can use the following block declaration:
#+begin_src perl :tangle "test.pl" :noweb tangle :padline no
