In preference to using Runtime/exec, you can use clojure.java.shell/sh and write your password to the stdin of the process using its :in argument. Another alternative might be to configure your /etc/sudoers to not require a password when running the shutdown command for the user that is making this call. --Aaron -- You received this message because you are subscribed to the Google Groups "Clojure" group.
