Anyway, the funny thing is, I had done rpm > -qa | grep mysql* and as you pointed out had gotten > the wrong results. Actually, it was not grep which was misleading you, it was the shell. Once you understand that commands only execute after the shell has processed all the tokens, things become much clearer. On your case, the shell expands the '*' before grep sees it, and what happens is that grep ends up receiving different args than the ones you thought it was going to use. > I have been using grep for years and I never knew what > you pointed out. Quite humbling. I am affraid you probably have been getting wrong grep results all this time... besides 'man bash', this nice doc could prove to be extremely helpful: 'Advanced Bash Scripting Guide'. Very nice piece of documentation, you will find it on www.tldp.org under 'Guides' (can't give you the exact URL right now because TLDP seems to be down).
