BASH Processes

[Mike B.]

Dear all,

I'm using Octave 3.2.4 in Debian. Two quick questionso on starting processes 
with system:

1. When issuing 
sleep 20 & 

from the bash commandline it immediately returns to the prompt (runs in the 
background) but when doing 
system( "sleep 20 &" )

from octave it waits for 20 sec. before returning. Why is that?.

2. When starting a process in the background bash returns the process ID (PID), 
for example:
sleep 20 &
[1] 20885

so 20885 is the PID. How can I read this output in octave?. The `system' 
command returns a different PID (not of the actual process started).

Thanks,
Mike.
