Print a triangle using * in a Bash script

Hello coders! Hows it going? Today we'll see a basic simple shell script to print a triangle using asterisk * only. Here's the code to do that :

#!/bin/bash

# Simple program to print a triangle using * of height 10

star="*"

for i in {1..10}

do

echo "$star";

star="$star *"

done

You see basically, all we are doing is append a * to itself recursively. Here we are using a basic for-loop to print a triangle of height 10. You can change the height as per your requirement, as needed.

Output :

*

* *

* * *

* * * *

* * * * *

* * * * * *

* * * * * * *

* * * * * * * *

* * * * * * * * *

* * * * * * * * * *

Cheers!
