Instead of reading line by line, you can slurp in the contents of the entire file into a scalar variable and then look for a match against an array of strings. 
local $/ = undef;
open(FH,"<","test.txt") or die "Could not open the file due to $!";
my $fcontent = <FH>;
close FH;

foreach (@typedefs) {
  if ($fcontent =~ /$_/){
          # perform various actions here if line match
  } 
}
