=INVESTIGATION 1: BASICS OF REDIRECTION=
<span style="color:red;">'''ATTENTION''': This tutorial will provide additional '''practice''' with the necessary skills The due date for successfully completing this weeks segment of your '''assignment''' and tutorial (i.e. tutorial 5) is not worth marksby March 10 @ 11:59 PM (Week 8).</span><br><br>
In this investigation, you will learn how to redirect '''standard input''', '''standard output''' and '''standard error''' when issuing Unix / Linux commands.
# Press <span style="color:blue;font-weight:bold;font-family:courier;">ctrl-d</span> to exit the command.<br><br>
# Issue the '''cat''' command to view the contents of the file: '''output3.txt'''<br><br>
# Issue the following Linux command: <span style="color:blue;font-weight:bold;font-family:courier;">cp ~murray.saul/uli101osl640/cars .</span><br><br>
# Issue the '''cat''' command to view the contents of the '''cars''' file.<br><br>
# Issue the following Linux command: <span style="color:blue;font-weight:bold;font-family:courier;">cut -c1-10 cars</span><br><br>What did this command do?<br><br>
# Issue a Linux command to view the contents of the file called '''output.txt'''<br><br>What does ''grouping'' do when issuing multiple Linux commands (separated by a semi-colon ";") that uses redirection?<br><br>
# Issue the following Linux pipeline command (using \ at the end of most lines):<br><span style="color:blue;font-family:courier;font-weight:bold">echo "This will be split over multiple \<br>lines. Note that the shell will realize \<br>that a pipe requires another command, so \<br>it will automatically go to the next line" |tr '[a-z]' '[A-Z]'</span><br><br>Did the command work? What is the purpose of issuing a Linux command in this way?<br><br>
# After you complete Complete the Review Questions sections to get additional practice, then work on your '''online assignment 2'''<br>and complete '''section3''' labelled: '''Redirection and Pipes'''.
