|
|
- Conditional blocks start with `if` and end with the inversion `fi` (this is a common syntactic pattern in bash)
|
|
|
|
|
- The conditional expression must be placed in square brackets with spaces either side. The spaces matter: if you omit them, the code will not run
|
|
|
|
|
- We designate the code to run when the conditional is met with `then`
|
|
|
|
|
- We can incorporate else if logic with `elif`
