I should read documentation before hitting user lists, but I like the gentoo user list for good reasons. The notes about zsh are greatly appreciated, but as long as I command the ability to take the time to learn well documented things, then if nothing else, it's a great learning experience. Using gentoo for me is largely motivated by this personal philosophy, and I changed from bash not because I dislike it but because I wanted to try something new. For example, just reading your response I've learned more about how the path works that I didn't know. I'm over my head right now for other work that's more pressing, but it seems like I should be able to get zsh running properly by next week. Regarding Helmut's comment: > What is echo $SHELL saying? > Here, is says /bin/zsh > and your examples works just fine. This is a useful suggestion, but I had tried this and confirmed the same output you report. So the problem is buried deeper in my lack of knowledge about the operation of shells. Thanks! ~daid
