But it is stty, not tty, which fails to be found. And stty is (normally) in /bin. So it looks a lot like /bin (and probably /sbin) is missing from the PATH. This could be related to the long-advertised switch to a unified /usr tree. Perhaps Ubuntu went ahead with that switch but some packages haven't been updated to reflect it? One other thing which springs to mind is the distinction between login, interactive, and other shells. Double-check in which shell startup file you set the PATH. BTW, plain text (not HTML) would be appreciated. -- Please *no* private Cc: on mailing lists and newsgroups Personal signed mail: please _encrypt_ and sign Don't clear-text sign: http://primate.net/~itz/blog/the-problem-with-gpg-signatures.html
