Hi everyone - I just have some quick questions about bash shell scripts. I'm writing a simple menu system for a friend who wants to use my system. First, can I write functions within a bash shell? Right now I have a main menu which calls a different script fro each additional menu. This I suppose can take up processor time since it spawns a bash shell for each. SO - can I have functions, one for each menu, in a single shell script. (Im sure I can, just dont know how) Second, is it possible to capture ^C and such so that a person can't exit out of the menu, or if they could, that at least it would output a message telling them how to get back to the menu? Third, this is probably also REALLY simple, but I'm a beginner. I am putting a prompt for each menu, as such: Command > _ But the cursor is always where the '_" is here, since I use the echo command. Is there a way to keep the cursor right after the Command >_ ? I know that this would probably be better sent to a newsgroup on shell programming, but I don't have usenet access right now. Thanks everyone!
