The “if” statement is used to execute different code blocks based on whether a condition is true or false.
The syntax format of the if statement is: if [condition]; then [commands]; fi. If the condition is met, the code in commands is executed; otherwise, it is skipped.
The if statement can be used with elif and else to support multiple condition evaluations.
Conditions in if statements can be evaluated using test commands such as test, [ ], or [[ ]].
The conditions in an ‘if’ statement can include comparison operators, logical operators, string comparisons, and so on.
When an if statement is executed, it will run the corresponding code block based on whether the condition is met or not, thereby controlling the flow of the program.
