You should checkout proces output to make sure, but I'm betting that sudo is opening a tty to read the password and not getting it from stdout. The properly solution here, here, may be to define shutdown as a sudo action for your user ID which does not require a password.
Well yeah but then only me can use it...it will not work on another machine! On 07/05/12 16:16, Aaron Cohen wrote:

Same here...i want this function to work across different machines/op-systems.
I think input redirection (the "|" you have there) is a construct of your shell rather than the OS, so you have to wrap that in a call to bash or whatever shell you prefer.
How would i do that? I thought the command i need to pass in ".exec()" is simply the command i would type in my terminal (windows or unix)...and i know that the command works at least on my ubuntu...
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.
Now that sounds more sensible but it means that the consumer has to have clojure...what if i was to aot-compile the function with gen-class to pretend it is plain Java?
