Left today's meetup myself around 3:15pm, so don't know what happened after I left, but here are a few follow-up resources and pieces-of-info after what happened when I was there.
1. The learn-the-Linux-commandline resource The Linux Command Line; A Book By William Shotts http://linuxcommand.org/tlcl.php/index.php
The main link from the book's site is the PDF tutorial TLCL version 17.10 freely downloadable under the Creative Commons license thru SourceForge's http://sourceforge.net/projects/linuxcommand/files/TLCL/17.10/TLCL-17.10.pdf/download
2. Michael P's incredibly awesome 'Introduction to Shell Programming http://www.rawbw.com/~mp/unix/sh/
* over 80% of everything you ever needed or wanted to know about shell programming in under 80 minutes
* the top stuff you need and want to know about shell programming
* learning shell programming in 6 pages or less
Note: Might be good/better to start learning some shell basics via using Units 1 thru 3 of the TLCL-17.10 PDF tutorial first before going to Michael P's powerful Shell Programming.
3. The somewhat humorous but surprisingly serious cartoon(s) of _not_ giving the Customer what they really needed; tree swing Evolution of a systems project, http://projectcartoon.com/cartoon/1111
In the case of what actually happened this afternoon to someone needing help with their laptop for installations of a user-friendly Linux distro + GUI/desktop + apps, one or two people kept emphatically insisting upon quite INappropriate advice for "What the customer really wanted" and overwhelming that person with TMI (DuckDuckGo search for "TMI") . Sure, there are other variants of this tree swing project management cartoon as well, such as at least https://amalgamated-contemplation.com/wp/wp-content/uploads/2016/06/Project-Cartoon-tree-swing-project-management-cartoon.png
The point is, substitute "SysAdmin" and/or "DevOps person" for the relevant references to Programmers in the tree swing cartoons and I think most people will get an accurate idea of what happened.
Please feel free to hop in here (Michael P, Rick M, others) and share your other keen thoughts, insights and suggestions on the above!
