in reply to Unwanted interpolation in backquoted string

Something like 
open(FILE, $file) or die "$!";
my @file = <FILE>;
close(FILE);
foreach (@file) {
   if (m/$val[0]/) {
      $tmp = (split /\s+/,$_)[1];
      print $tmp . "\n";
   }
}

but the actual problem with the back quotes is that $2 should be escaped. (s/$2/\$2/) The reason is that you want awk to interpret $2, not Perl.

    I think you mean s/\$2/\\\$2/ :)
