Shell scripting is so essential for Linux administration that this course has created a shell script for every lab for this course that a student must download and run in order to check their work. If you have performed the lab correctly, then you will get a series of<b><code><span style="color:#00ff00;font-size:1.2em;">OK</span></code></b> messages and you can proceed with the SIGN-OFF for lab1. On the other hand, if there were errors, then a <b><code><span style="color:#ff0000;font-size:1.2em;">WARNING</span></code></b> message will appear with general suggestions that you will need to fix on your centos1 VM in order to have your OPS235 sign-off in this lab in order to proceed to the next lab.
