Here's a Python example:
```python
def factorial(n):
    if n <= 1:
        return 1
    return n * factorial(n-1)

print(factorial(5))
```

And JavaScript:
```javascript
function fibonacci(n) {
    if (n <= 1) return n;
    return fibonacci(n-1) + fibonacci(n-2);
}
console.log(fibonacci(10));
```

And a bash command:
```bash
echo "Hello from bash"
ls -la /tmp
```
