→INVESTIGATION 2: REDIRECTION USING PIPES
# Confirm that you are still located in the '''~/redirect''' directory.<br><br>
# Issue the '''ls''' command to view the contents of your '''~/redirect''' directory.<br><br>The '''problem''' with creating temporary files, is that they take up space on your server,<br>and should be removed.<br><br>
# Issue the following Linux command to remove all temporary files in your ''redirect'' directory: <span style="color:blue;font-weight:bold;font-family:courier;">rm -r ~/redirect</span><br>and confirm that you have removed this directory and its contents.<br><br>'''NOTE:''' You will be issuing a '''pipeline command''' which will use the pipe symbol "|"<br>that will send the stdout from a command as stdin into another commandwithout having to create temporary files.<br><br>
# Issue the follow Linux '''pipeline command''': <span style="color:blue;font-weight:bold;font-family:courier;">ls /bin | more</span><br><br>What happened?<br><br>
# Issue the following Linux '''pipeline command''': <span style="color:blue;font-weight:bold;font-family:courier;">ls /bin | who</span><br><br>What happened? Why is the result different than antipated?[[Image:pipe-diagram-1.png|thumb|right|350px|]]<br><br>'''NOTE:''' When issuing pipeline commands, commands to the right of the pipe symbol must be designed to accept stdin. Since the who command does not, you did NOT see the contents of the '''/bin''' directory but only information relating to the ''who'' command. Therefore, the '''order''' of which you build your pipeline command and the '''type of command''' that is used as a ''filter'' is extremely important!<br><br>
