Conditionals - if

The if statement in shell scripting allows you to execute different blocks of code based on whether a certain condition is true or false. It's a fundamental control flow mechanism that enables scripts to make decisions and behave differently depending on the input or state of the system. The if statement evaluates an expression, and if the expression is true, a specific set of commands is executed. Otherwise, the script can optionally execute a different set of commands defined in else or elif blocks.
