Specifically, you can use "perldoc -q" to search through the FAQ that comes with perl. In this case I tried: perldoc -q two array diff and the second question that comes up is "How do I compute the difference of two arrays?" The other (command-line) way to get to it is to do "perldoc perlfaq" to see the list of the FAQs. One of them is "perlfaq4 - Data Manipulation" which sounds promising, and indeed "perldoc perlfaq4" contains the same entry I got to from the "perldoc -q ..." command above. Actually now that I look at it, "perldoc perlfaq" contains a list of all the questions. perldoc.perl.org is another interface you can try for similar results. --Brock -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
