I want to run command line on my linux rig.

I've setup all the projects on it so far so I was wondering if the following command would work and what others that run if command line have.

Been using http://boinc.berkeley.edu/trac/wiki/BoincCmd as a guide...

My command I want to use is:-

Code:
boinc_cmd --read_global_prefs_override
Also what happens if I run another command, like
Code:
boinc_cmd --get_results
when the first command is already running?
