→INVESTIGATION 1: CREATING A SHELL SCRIPT
# '''Login''' your matrix account.<br><br>
# Issue a command to '''confirm''' you are located in your home directory.<br><br>We want to create a Bash Shell script to welcome the user. Let's first provide some useful tips in terms<br>of selecting an appropriate name for the shell script.<br><br>
# Issue the following linux command to check if your intended shell script name<br>is already exists to be run automatically from the Bash shell:<br><span style="color:blue;font-weight:bold;font-family:courier;">which hello</span><br><br>You should notice that there is no output and therefore, this shell script name can be used.<br>On the other hand, if you wanted to create a file called sed, then the '''which sed''' command <br>would indicate it is already being used by the shell and that '''sed''' wouldn't be an appropriate shell script name to use.<br><br>
