By the way. The rpm man pages shows a '+' after the package name, but I can't see anywhere what that's for. I don't use the '+', and it works anyway.
What's the '+' for?
The '+' just means "one or more" of whatever precedes it. If the man page says [package name]+ it means you can have one or more package names on the command line. It's taken from the so-called regular expressions, where '*' means "zero or more" and '+' means "one or more". It's not very common in man pages, but regular expressions tend to crop up here and there in linux/unix so it could be good to know. regards Anders
