If statements

• 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
