## Argument Check
### Objectives
Note: assume the script is executed with an argument
1. Write a script that will check if a given argument is the string "pizza"
2. If it's the string "pizza" print "with pineapple?"
3. If it's not the string "pizza" print "I want pizza!"
### Solution
```
#!/usr/bin/env bash
[[ ${1} == "pizza" ]] && echo "with pineapple?" || echo "I want pizza!"
```
