Differences from GNU cat
- No binary file support.
- A line is considered terminated by either a
CR(carriage return), aLF(line feed), aCR+LFsequence (DOS line ending). - A line ending is automatically appended to the last line of any read file.
- The
U+notation is used instead ofM-for non-printing characters.
