You could first open the file, then read the byte in from the file handle, then inspect the byte.

# open a file
open MYFILE, '<myfile.bin' or die 'can not open file';

# read a byte
my $byte;
read MYFILE, $byte, 1; # do perldoc -f read to see full doco

# check the byte
if ($byte > 0x30) {
  print "Byte is greater than 0x30\n";
} else {
  print "Byte is less than or equal to 0x30\n";
}

# close the file
close MYFILE;
