# Use the '''more''' command to view the contents of the text file called '''for-1.bash''' (eg. <span style="color:blue;font-weight:bold;font-family:courier;">more for-1.bash</span>)<br><br>As you should have noticed from ''tutorial 10'' that the '''for''' loop can use a '''list'''.<br>You can also use the for loop with positional parameters stored as arguments from an executed shell script.<br>We will revisit this now.<br><br># Use the more command to view the text file called '''for-2.bash''' (eg. <span style="color:blue;font-weight:bold;font-family:courier;">more for-2.bash</span>)<br><br>If you are using the nano text editor, refer to notes on text editing in a previous week in the course schedule.<br><br># Run your shell script by issuing: <span style="color:blue;font-weight:bold;font-family:courier;">./for-2.bash 10 9 8 7 6 5 4 3 2 1</span><br><br>You should notice the script looped for each argument following the shell script.<br><br>You can also use the for loop with a list using '''command substitution''' - this is an effective technique to loop within a shell script.<br><br>
