→INVESTIGATION 2: USING THE LINUX SHELL / ONLINE ASSIGNMENTS
# '''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 copy | 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>'''NOTE:''' You are Do '''NOT required to change your Matrix password for this tutorial. The Matrix server is "synched"<br>with ''' run the ''my.senecacollege.ca serverpasswd'', so it is better to have your command. Your Matrix password is changed at the same time<br>that automatically when you change your '''myseneca''' password.<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''' to correct syntax errors while typing Linux commands PRIOR to pressing the ENTER key.<br><br>
