: To match compatibility of scripting elements for current OPS235 labs. Emphasis will be placed on practicality, creativity, and listing scripting items that can be used to match and compare towards existing scripting course OPS435 to provide information for CNS / CTY curriculum discussions. This resource particular WIKI will concentrate initially with shorton long-term "fits" (i.e. no major structural changes to course from existing learning outcomes, topics and core skillson OPS335 and OPS435 courses as well as other courses in the OPS Stream).

Lab 1 could be modified to have students generate a report regarding the collection of Linux information after an install. Certainly '''command substitution''' could be taught and to reinforce '''redirection''' >> to add content to a filename (i.e. not over-ride). It would be interesting to expose students to the '''zenity''' command to allow a menu to give user choice of report elements to include in the generated report. Perhaps a link to a "fancy" Bash shell script to generate a web-page so students can view the contents in a nice format.

::Definitely a shell script to demonstrate the automation of IP tables (simpler example). I assume would be great benefit to OPS335 course that students be exposed to this to help automate their management of firewalls in OPS335.

::Perhaps add *Add element to existing assignment to develop an asset inventory for installed Linux system. Perhaps use html template to create nice-looking report based on required content.<br><br>::*Add element to create a shell script to backup VMs from /var/lib/libvirt/images to a USB device.

::*Add a shell script requirement to automate compilation of source code. For example: obtaining a zipped tarbar via url ('''wget'''), decompression zipped tarball, change to source directory, logic to see if '''./configure''' command needs to be run, compile and run software or provide error or problems of failure to install software.
