# 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.
