Linux CLI Basics #

• Gold-standard tutorial: Command Line Crash Course
  • By Zed Shaw
• Also-good, is Learning the Shell
• Best in class, video lecture: The Missing Semester: Course Overview + the Shell

Commands #

• pwd
• cd
• ls
• clear
• cat
• less
• tail
• touch
• cp
• mv
• rm
• mkdir
• rmdir
• which
• help
• man
• find
• grep
• echo
• exit
• sudo

Optional #

• hostname
• export
• env
• apropos
• xargs
• file
• type

Proposed Lab #

• Sean L’s python CLI text-adventure game?
• Terminus CLI Game ?
• Live screen session share where a coach/mentor asks questions to determine whether or not agent is proficient in the terminal, answers questions, and shows appropriate answers, if agent is confused?
  • This should probably only take about 20-30 minutes.
  • This is similar to the practical exams that London taxi-drivers have to take where they have an oral exam given by a proctor.
  • How else do we measure true understanding/proficiency with basic CLI skills?

...

IIRC some wp-cli is covered in training, but a more in-depth treatment of common tasks done with the wp-cli might be covered here.

I’m not sure if this would be useful, I need to review this guide more in depth, but this was recommended to me by a WP dev, so could be a good intro to the WP application which may facilitate troubleshooting WP issues.
