# Issue the same Linux command that you issued in '''step #12'''.<br><br>What did you notice?<br><br>
# Issue the following Linux command: <br><span style="color:blue;font-weight:bold;font-family:courier;">scp myfile.txt yoursenecaid@matrix.senecacollege.ca:</span><br><br>Where do you think this file was copied to on your remote server?<br><br>
