→INVESTIGATION 4: USING START-UP FILES
# Issue a Linux command to <u>confirm</u> you are located in the '''home''' directory.<br><br>
# Use the '''more''' command to view the contents of the '''default start-up''' file called '''/etc/profile''' <br><br>This file contains the '''default settings''' when you open your Bourne shell (eg. if issuing the command '''sh''').<br><br>
# Use the '''more''' command to view the contents of the start-up file called '''/etc/bashrc'''<br><br>This file contains the '''default settings''' when you '''open your Bash shell''' (eg. if issuing the command '''bash''').<br><br>Since we are using the '''Bash shell''' by default, let's create a '''customized Bash start-up file'''.<br>This startup file is located in your '''home''' directory using the name "'''.bashrc'''"<br><br>Let's move your <span style="font-weight:bold;font-family:courier;">.bashrc</span> file to prevent '''accidental overwrite'''.<br><br>
# 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>
