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. This scripting element could easily be added to assignment #1.<br><br>OPS435 ElementsIt is recommended to add to lab1 a simple '''step-by-step procedure to generate a simple text-based report in a shell script''' (eg. '''text-report.bash'''), but also have students use '''wget''' command to download, set execute permissions and run more sophisticated shell scripts (eg. '''report.bash''' and '''report2.bash''')  :'''Example of Simple text-based report (text-report.bash):''' {|cellpadding="15" width="100%"|-|</blockquote><br><br>Example of Shell script Demo: [ [[lab1 Shell Script Demo|report.bash]] ]<br><br>Listing of Scripting Skills from Demo Listed Above:<blockquote><ul><li>'''if''' statement</li><li>'''exit'''command substitution</li><li>USER '''Environment Variable''' (shell grammar?)</li><li>'''redirection''' (both &gt; vs and &gt;&gt;)</li><li>'''zenity'''</li><li>'''IO Stream vs Graphical Interactionfor''' (eg. zenity)loop</li><li>'''Scripting Samples (View and adaptcommand substitution'''</li><li>'''sed''- don't "re-invent the wheel completely")</li><li>Exposure to '''forset''' loop with command ('''positional parameters''' )</li></ul></blockquote><br><br>Connection with ULI101 Scripting Skills (Course Outline):<br>Connection with OPS435 Scripting Skills (storing checkbox selectionsCourse Outline) :<br><br>'''Practical Consideration for reportscripting in lab1:''' Do students create simple bash shell script, add elements, then have them copy and paste, then run this more complex script?
