These videos are not to be taken as a comprehensive overview of the UNIX shell, rather positioned as 'minimum viable scaffolding' in advance of stepping foot on a server. The videos draw from 25 years of system administration experience, and over 15 years teaching the craft. (Please note this collection of videos is still growing - more to come!)
