You described the issue and cause better than I did :) I didn't know about the ANSI behavior, interesting. >FWIW, if you need a fool-proof way to convert a man page to plain old ASCII with no escapes at all, it's easiest just to redirect the output of "man" to a file: > man ls > ls.txt IIRC, even with that way, the control chars still appeared in the file (at least on some Unix version), which is why I wrote the script in the first place. |
