Virtual Box Guest Additions Install - Linux (CentOS - Ubuntu)

Question

how to check whether Virtualbox Guest Additions have been installed on CentOS or any linux distro for that matter ?

I have a few Linux based VMs in Virtualbox and have forgotten whether I had installed Guest additions or not :-)

Would be grateful. Kind Regards

ps -A

Look for instances of "VBoxClient" (may be a few).

	Thank you for the answer, is there a way I can sort the output of that command alphabetically ? I have tried `ps -A \| grep "VB"` - still learning the command line :-) - thanks again ! – rihatum Oct 29 '10 at 9:49
	ps -A \| grep "VBoxService" - should bring it down to a single "hit." – user48838 Oct 29 '10 at 17:33
