Conditional Statements (if, else, elif)

Implement decision-making logic in your scripts using 'if', 'else', and 'elif' statements for dynamic behavior.

Why Conditionals Matter

In Bash scripting, sometimes you need your script to make decisions. Imagine a script that performs different actions based on user input or a file's existence.

This is where conditional statements come in! They allow your script to execute specific blocks of code only if certain conditions are met.

The Basic 'if' Statement

The simplest conditional is the if statement. It checks a condition, and if it's true, a block of commands is executed.

The syntax is:

if [ condition ]
then
# commands if condition is true
fi (marks the end of the if block)
