> rev (1) - reverse lines of a file > tac (1) - concatenate and print files in reverse
Perhaps these could be rephrased to remain short while being a little less ambiguous. I'd suggest: rev (1) - reverse the order of characters on every line tac (1) - concatenate and print lines in reversed order The man page for rev could also state that it deals with unicode characters. In other words, it does not just reverse the bytes; it reverses logical characters even if they are multiple bytes in length. This means in particular that "rev" can give an error when applied to eg a binary file, which should be documented in the ERRORS section of the man page. Also, because of this issue, "tac | rev" or "rev | tac" do not serve to reverse all the bytes of the input. An option to defeat character decoding deal with bytes might be desirable, but there is no such option. -- Barak A. Pearlmutter <[EMAIL PROTECTED]> Hamilton Institute, NUI Maynooth, Co.
