what do you mean by assuming netscape is in your path?
That you can execute netscape without having to type
the full path to it. If that still doesn't ring a
bell, consult your local system administrator. He
may have some introduction to UNIX books for you.
At first read through (especially your questions to Abigail-II), I assumed you were a troll, but after looking at several of your other nodes, it looks like you need to follow nite_man's advice in Re: save form and also learn How to RTFM. An afternoon studying How (Not) To Ask A Question would not be time wasted either. And before asking a question please check Super Search and Google.
And one final nit... The total lack of formating in your original post makes me think you haven't spent quite enough time studying the Monastery's Writeup Formatting Tips.
