chop removes the last character of a string and returns it.
  it is mor efficient than s/// because it does not scan.

chomp removes any trailing string that corresponds to the current
   $INPUT_RECORD_SEPARATOR, cr lf or both.

when in doubt about removing dos,unix or mac eol i use something like
   $ln =~ s/[\x0a\x0d]*$//;
but this fails the save every microsecond requirement, as does chomp.
