Tools: Linux Fundamentals - Part 7: Bash Scripting (If Statements)

If Statements ## If...Else Statements ## Nested if Statements If statements execute code base on a condition. If the condition is true, the code block will run. The condition is enclosed in square brackets [ ] and the statement ends with fi, which is if spelled backward, marking the end of the if block. Example: Basic If Statement. If...else statements provide a way to execute one block of code if a condition is true and another block if it is false. The else keyword introduces the alternative block, and the statement ends with fi. Example: If...Else Statement Nested if statements allow you to place an if statement inside another if statement, enabling more complex logic. Each if block must be closed with its own fi. Example: Nested If Statement. Templates let you quickly answer FAQs or store snippets for re-use. Are you sure you want to hide this comment?
