# Use a text editor like vi or nano to create the text file called hello (eg. <span style="color:blue;font-weight:bold;font-family:courier;">vi hello</span>)<br><br>
# Enter the following two lines in your shell script, replacing "your name" with your actual name:<br><span style="font-family:courier;">clear<br>echo "Hello Your Name"</span><br><br>
# Save your editing session and exit the text editor (eg. with vi: press '''ESC''', then type ''':wx ''' followed by '''ENTER''').<br><br>
# Issue the following linux command to run your shell script in your current directory:<br><span style="color:blue;font-weight:bold;font-family:courier;">./hello</span><br><br>You should notice an error indicating you don't have permissions to run the file.<br>You need to first add execute permissions prior to running the shell script.<br><br>
