For instance, it is excellent at parsing and manipulating tabular data. It operates on a line-by-line basis and iterates through the entire file.

Reading Input Files.

In this chapter, we will discuss shell loop control in Unix. So far you have looked at creating loops and working with loops to accomplish different tasks. Sometimes you need to stop a loop or skip iterations of the loop. In this chapter, we will learn following two statements that are used to.
