Bash Else If
In this topic, we will understand how to use else-if (elif) statements in Bash scripts to get our automated tasks completed.
Bash else-if statement is used for multiple conditions. It is just like an addition to Bash if-else statement. In Bash elif, there can be several elif blocks with a boolean expression for each one of them. In the case of the first 'if statement', if a condition goes false, then the second 'if condition' is checked.
