Q:

Find location of process running in top command

When I run 'top' I see a process running named "watchdog" I read up on watchdog via the man page ala Google but I don't have that program installed. I've done a whereis and checked the /dev file to no avail. Can someone point me to finding where this process is coming from?
I'm running Ubuntu Server 14.04 with virtual box, virtual box headless & 'no machine' installed. Almost every other application or program I run is within a VM on the server & they're all powered down at the moment. 

A:

The quick and easy (and classic) way to find the full command that was run is to do a grep through ps output:
[$]> ps aux | grep watchdog

However, I feel obliged to point out that this isn't the most reliable way, which would be
[$]> pgrep -fl watchdog
