Hi Johnathan, > Looking at the command you gave: > man -t bash | open -a preview -f I have 2 questions.
1. man bash or man -t bash. What is groff? From man, I don't become any wiser. It seems that man -t bash, will have man pass its output to groff, rather than to stout, while groff in turn, does pass it to stdout with a lot of modifications. What is it that I see, when I enter man -t? Groff is a front end for something else that I completely don't understand. Question here is: what are you doing, using man -t? 2. The output from man, traveling through gruff by means of the man -t option, is then piped into the preview command. So far so good. But what is the -f preview option for? I googled a lot but where do you find the preview mac command line options? Question here is: what is -f doing in preview? I understand the -a switch for open. If this were not in place, then the open command, a mac specific one I know now, would never know where to look. -a Specifies to look inside the applications folder, wherever that resides. Can you please answer my 2 questions above? It looks like each new answer poses new questions, but that will settle down over time I hope. Paul. On Feb 9, 2012, at 4:10 AM, Jonathan C.
