If you want to learn how to use Linux at the command line including the mysteries of vim and grep, I have been running FREE, instructor led, virtual Linux fundamentals courses. I've run two so far and have another session scheduled for this eveining. I'll be running the next one on 7/8th August in the evening between 7.00 and 9.30pm GMT. If you're interested please email me for an invite.

I underestimated the amount of admin involved in setting up even free courses but I think I'm on top of it now.
