Changes

::'''Scripting Demo (user account management):''' [ ].  ::Expose students to manipulate data files to efficiently create several user accounts at the same time. This topic should be teachable and emphasize the usefulness of the awk command. Zenity not really required in this case, and should move away from too many zenity examples: use shell scripts to assist the Linux admin. Perhaps have students create a bin directory in the /root account as a collection point of these shell scripts. Could use zenity to create a dialog box to select specific operations. Additional zenity dialog boxes can use text-boxes to obtain information such as username, fullname, etc. It is noted that other important user management operations like '''aging''' user accounts is not included (should this be included for example, temporary accounts for projects within an organization). <blockquote><blockquote>OPS435 Elements (Scripting Demo Contents):<blockquote><ul><li>x</li><li>x</li><li>x</li><li>x</li><li>x</li><li>x</li><li>x</li><li>x</li><li>x</li></ul></blockquote><br><br>
