Explain the while construct, and demonstrate how it can be used.
What will be an ideal response?
The while construct is a common loop construct used within shell scripts. The while construct begins with a test statement. As long as (i.e. while) the test statement returns true, the commands within the loop construct are executed. When the test statement returns false, the commands within the while construct stop executing. A while construct typically contains a variable, called a counter variable, whose value changes each time through the loop. For the while construct to work properly, it must be set up so that, when the counter variable reaches a certain value, the test statement returns false. This prevents the loop from executing indefinitely.The syntax of the while construct is as follows:whilethis returns truedothese commandsdone
