→INVESTIGATION 3: USING STARTUP FILES
# Let's move your .bashrc file to prevent accidental overwrite. Issue the following linux command:<br><span style="color:blue;font-weight:bold;font-family:courier;">mv ~/.bashrc ~.bashrc.bk</span><br><br>If you experience an error message "''No such file or directory''", just ignore since there is no startup file to backup.<br><br>
# Use a text editor like vi or nano to create the text file called '''~/.bashrc''' (eg. <span style="color:blue;font-weight:bold;font-family:courier;">vi ~/.bashrc</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>
# Enter the following lines in your shell script(the symbol [ is the open square bracket symbol):<br><span style="font-family:courier;">clear<br>echo -e -n "\e[0;34m"<br>echo "Last Time Logged in (for security):"<br>echo<br>lastlog -u $USER<br>echo<br>echo -e -n "\e[m"</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>
