What's your most commonly used command, on Linux?

 

I would probably say top -s. Whilst it doesn't do anything to change your server (except add a little load to it), it does allow you to monitor what's going on, on the server and see how well the machine is coping in terms of memory usage, CPU consuming scripts, etc.
