 :: This lab deals with software installation and introduction to LVM. Not certain shell scripting would benefit software installation with yum, since can use yum to install multiple instances of software. On the other hand, would be useful to expose students to '''shell scripts that manage LVM for practical situations''' (i.e. case scenarios - real world situations). Should consult with professors and industry SMEs to provide good examples of scripts involving LVM. LVM scripting example should be included in this lab since lab4 is a big lab and keeps students very involved.<br><br>[[Image:lab3_monitor_1.png|thumb|right|375px|When executed as '''root''' or using '''sudo'''Example command, allows for creation of many user accounts (stored in a user database in /root/new-users.txt]]'''Shell script DemoScript #1 (monitor Disk Space):''' [ [[lab3 Shell Script Demo 1|xhttps://scs.senecac.on.ca/~murray.saul/monitor-disk-space.bash monitor-disk-space.bash]] ] <br>(to be createdCourtesy: http://bash.cyberciti.biz/monitoring/shell-script-monitor-unix-linux-diskspace/)<br><br>'''Scripting Skills:'''<blockquote><ul><li>x'''df'''</li><li>x'''grep'''</li><li>x'''awk'''</li><li>x'''command substitution'''</li><li>x'''mail'''</li><li>x'''cut'''</li><li>x'''do-while''' loop</li><li>x</li><li>x'''Cron Tables'''(crontab)</li></ul></blockquote><br>
