:In the next investigation, you will use the '''sftp''' Linux command to transfer (i.e. copy) files between servers.<br><br>
=INVESTIGATION 2: USING SECURE FILE TRANSMISSION CONTROL PROTOCOL FTP =
In this section, you will learn how to use the '''sftp''' command to transfer files between Unix/Linux servers and perform some basic directory navigation/management operations.
<span style="color:blue;">'''NOTE:''' Since the only server account you have is your '''Matrix''' server, we will simulate using the '''sftp ''' command to transfer/copy from your '''Matrix''' server to '''<u>another instance</u> of your Matrix server'''. You are NOT required to edit your ''.bashrc'' file to make this work since you already performed that operation in the previous investigation.</span>
# Use a text editor to create a text file called '''thefile.txt'''<br><br>

# '''Save''' editing changes to the text files file and exit your text editor.<br><br>
# Change back to your '''home''' directory and confirm that you are located in your ''home'' directory.<br><br>Let's run a '''shell script''' to check to make certain that you created the correct directories<br>and that you created the '''myfile.txt''' file (with correct file contents) in the '''~/local''' directory<br>before learning to use the ''sftp'' Linux command.<br><br>
