In Linux shell scripting, the if-elif statement is used to test multiple conditions and execute different blocks of commands based on the result of these tests. The syntax is if condition1; then commands1 elif condition2; then commands2 else commands3 fi. If condition1 is true, commands1 are executed, if condition1 is false and condition2 is true, commands2 are executed, and if none of the conditions are true, commands3 are executed. An example usage could be to test whether a number is zero, positive, or negative using the if-elif statement. #linux #shellscripting
