Controlling the loop execution
The loop condition dictates when it should run and stop. Two Bash built-ins can change this behavior. Using them, we can interrupt the loop or skip its iteration. Let’s consider these built-ins in detail.
break
The break built-in stops the loop immediately. It is useful for handling an error and finishing an infinite loop.
Here is an example of using break. Let’s suppose we write a script that searches the specific array element by its value. We apply the loop to traverse the array. When we ...
