It already did. :) All the lines that start with kdeinit are stderr
output from a program that's shutting down. You already have a prompt
at this point. You could just start typing your command. Even though
the cursor is not at the [user@machinename dir] prompt, the shell still
thinks it's there because it ignores stderr from running programs.
The best way I know to show you this is this small program:
#!/bin/bash
. /etc/rc.d/init.d/functions
echo -n "Starting sleeper function"
echo_success
echo
(sleep 5 && echo -n "Completing sleeper function" && echo_success) &
It starts a process running in the background that sleeps for 5 seconds
and then prints some stuff. Notice where it prints the "completing"
message. Notice where it puts the cursor after the second OK. Just
type "ls" and it will list the current directory. The shell still
_thinks_ that the cursor is at the same spot.
Changet he last line to:
(sleep 5 && echo -n "Completing sleeper function") &
Same thing.
