+# Bash Hello World
+
+Once we have our `devdojo.sh` file created and we've specified the bash shebang on the very first line, we are ready to create our first `Hello World` bash script.
+
+To do that, open the `devdojo.sh` file again and add the following after the `#!/bin/bash` line:
+
+```bash
+#!/bin/bash
+
+echo "Hello World!"
+```
+
+Save the file and exit.
+
+After that make the script executable by running:
+
+```bash
+chmod +x devdojo.sh
+```
+
+After that execute the file:
+
+```bash
+./devdojo.sh
+```
+
+You will see a "Hello World" message on the screen.
+
+Another way to run the script would be:
+
+```bash
+bash devdojo.sh
+```
+
+As bash can be used interactively, you could run the following command directly in your terminal and you would get the same result:
+
+```bash
+echo "Hello DevDojo!"
+```
+
+Putting a script together is useful once you have to combine multiple commands together.
