Hi!
I'd like to run a "sudo" command from Common Lisp. The following works:
--8<---------------cut here---------------start------------->8--- (uiop:launch-program '("sudo" "-S" "ls" "/root") :input :stream :output *standard-output*) (format (uiop:process-info-input #v1) "MY-PASSWORD~%") (finish-output (uiop:process-info-input #v1)) --8<---------------cut here---------------end--------------->8---
Note that I'm using the "-S" parameter of sudo. From the man page:
Write the prompt to the standard error and read the password from the standard input instead of using the terminal device.
Without it, "sudo" terminate immediately.
Somehow, Emacs _does_ support calling the sudo process without the "-S" flag. Try this:
--8<---------------cut here---------------start------------->8--- (make-process :name "dummy" :command '("sudo" "ls" "/root")) --8<---------------cut here---------------end--------------->8---
and the "sudo" process is kindly waiting for input in the background.
Any idea why that is? Is it be possible to do the same in Common Lisp?
Cheers!
