→‎INVESTIGATION 1: CREATING A SHELL SCRIPT

# '''Login''' your matrix account.

# Issue a command to '''confirm''' you are located in your home directory. We want to create a Bash Shell script to welcome the userby their username. Let's first provide some useful tips in terms of selecting an appropriate name for the shell script.

# Issue the following linux command to check if your intended shell script name is already exists to be run automatically from the Bash shell: which hello You should notice that there is no output and therefore, this shell script name can be used. On the other hand, if you wanted to create a file called sed, then the '''which sed''' command would indicate it is already being used by the shell and that '''sed''' wouldn't be an appropriate shell script name to use.

# Use a text editor like vi or nano to create the text file called hello (eg. vi hello)

# Enter the following two lines in your shell script, replacing "your ~~name~~-username" with your actual name: clear echo "Hello ~~Your Name~~your-username"

# Save your editing session and exit the text editor (eg. with vi: press '''ESC''', then type ''':wx''' followed by '''ENTER''').

# Issue the following linux command to run your shell script in your current directory: ./hello You should notice an error indicating you don't have permissions to run the file. You need to first add execute permissions prior to running the shell script.

# Issue the following linux command to add execute permissions for your shell script: chmod u+x hello

# Re-run your shell script: ./hello You should now see your screen clear and displays a greeting to you using your ~~name~~username.
