# Make certain that you are logged into your '''Matrix''' account and are located in your '''home''' directory.<br><br>
# Issue the following Linux command:<br><span style="color:blue;font-weight:bold;font-family:courier;">mail yoursenecaid@myseneca.ca</span><br><br>
# When prompted, enter the '''subject line''': <span style="color:blue;font-weight:bold;font-family:courier;">Test Message</span><br>and press <span style="color:blue;font-weight:bold;font-family:courier;">ENTER</SPAN><br><br>
# In the email message '''BODY''' section, type the following text displayed below:<br><span style="font-weight:bold;font-family:courier;">This is a test email message</span><br><br>
# Press <span style="color:blue;font-weight:bold;font-family:courier;">ctrl-d</span> to send your email message.<br><br>Did any output display after you sent this email message? If so, what you do think it stands for?<br><br>
# Switch to your email and check your Seneca email for messages. Did you receive that email message?<br><br>
# Check your email to see if you received your email message. If you did, what do you notice?<br><br>
# Return to your shell and issue the following Linux command:<br><span style="color:blue;font-weight:bold;font-family:courier;">mail -s "email with attachment" yoursenecaid@myseneca.ca < ~/local/thefile.txt</span><br><br>What happened?<br><br># Check your email to see if you received your email message. If you did, what do you notice?<br><br>You should have noticed that there was '''NO''' customized '''subject line''', since you redirected stdin from the file, thus there was no ability to send a subject line.<br><br>You can use the -s option, followed by text (in quotes) to specify a subject line.<br><br># Return to your shell and issue the following Linux command:<br><span style="color:blue;font-weight:bold;font-family:courier;">mail -s "email with attachment" yoursenecaid@myseneca.ca < ~/local/thefile.txt</span><br><br># Check your email to see if you received your email message. If you did, what do you notice this time?<br><br>
# After completing this INVESTIGATION, perform the LINUX PRACTICE QUESTIONS at the end of the tutorial.<br><br>
