# Navigate through the man utility for the '''ls''' Linux command and note the '''option letters''' that correspond to the following descriptions:<br><ul><li>"'''use a long lising format'''"</li><li>"'''do not ignore entries starting with .'''" (i.e. hidden files)</li><li>"'''sort by file size'''"</li><li>"'''append indicator (one of */=>&|) to entries'''" (i.e. type of file)</li></ul><br>
# Exit the man utility for the ''ls'' command.<br><br>
# Issue the '''ls''' command for <u>each</u> of those option letters you noted in '''step 45''' to see how this command differs for each option.<br><br>'''NOTE:''' The '''man''' utility can be used with the '''-k''' option to help list Linux commands that match a text pattern<br>that is contained within the help screen for a Linux command.<br><br>
# '''Pipeline commands''' can be used to filter-out unnecessary output. In the next command that you will be issuing,<br>the output from the '''man -k''' command, is sent into the '''grep''' command to ''filter'' (i.e. ''trap'') only output that matches the pattern "8"<br>(The number "8" refers to the category of type of command - in this case, administration commands).<br><br>We will learn more about pipeline commands later in this course.<br><br>
# Issue the following Linux pipeline command: <span style="font-family:courier;color:blue;font-weight:bold">man -k user | grep 8</span><br><br>How does this ''pipeline command'' make it easier to obtain information regarding man command?<br><br>
# If you wish to change your password, you can change it by issuing the command: <span style="font-family:courier;color:blue;font-weight:bold">passwd</span><br>What option for the passwd command can be used to change user info (such as name)?<br>'''Hint:''' use the '''man''' command for '''passwd'''.<br><br># Press the letter <span style="font-family:courier;color:blue;font-weight:bold">q</span> to exit the man command.<br><br>'''NOTE:''' Do '''NOT''' run the ''passwd'' command. Unique for this college, your Matrix password<br>is changed automatically when you change your '''myseneca''' password.<br><br><br># Press the letter <span style="font-family:courier;color:blue;font-weight:bold">q</span> to exit the man command.<br><br>You will now learn how to perform '''command line editing'''<br>to correct syntax errors while typing Linux commands PRIOR to pressing the ENTER key.<br><br>
'''Command Line Editing'''
'''Running a Shell Script to Check Student Online Tutorial Participation'''
These programs (known as Shell Scripts) will check your work and offer feedback if you made mistakes, so you can make corrections.<br>Making corrections (i.e. troubleshooting) and re-running these checking programs until you are successful will help students<br>gain "hands-on" experience as well as "trouble-shooting experience.
simulate a quiz:

Your instructor may take-up these questions during class. It is up to the student to attend classes in order to obtain the answers to the following questions. Your instructor will NOT provide these answers in any other form (eg. e-mail, etc).
