ELIF (ELSE IF) statement

ELIF is the keyword used for the ELSE IF statement in bash scripting. If in a loop if more than two conditions exist which can not be solved only by using IF-ELSE statement then ELIF is used. Multiple ELIF conditions can be defined inside one if-else loop.

ELIF syntax:

if [ condition1 ]
then
       statement1
 elif [ condition2 ]
then
       statement2
 elif [condition3 ]
then
       statement3
else
      statement_n
fi

Code:

#!/bin/bash
 # Initializing the variable
 a=20
 if [ $a < 10 ] 
then  
      # If variable less than 10    
      echo "a is less than 10" 
elif [ $a < 25 ] 
then  
      # If variable less than 25  
      echo "a is less than 25" 
else   
     # If variable is greater than 25   
     echo "a is greater than 25"  
fi 

Output:

a is greater than 25

In this article, we will discuss how to write a bash script for the Else If statement.

Conditional statements: The statements that perform specific functions based on certain conditions are called conditional statements. In bash scripting, we have several conditional statements like IF, IF-ELSE, IF-ELSE-IF, etc. Every statement has its way of working and according to the need, we use them.
