while loop

Using Looping Structures I

while loop

You can also use looping control structures within a shell script. Looping structures come in three varieties: the while loop, the until loop, and the for loop.

 A while loop executes over and over until specified condition is no longer true. The structure of a while loop is as follows:

while condition
   do
                script commands
    done


A while loop will keep processing over and over and over until the condition evaluates to false.
