Control Flow StatementsThe statements inside your source files are generally executed from top to bottom, in the order that they appear. Control flow statements, however, break up the flow of execution by employing decision making, looping, and branching, enabling your program to conditionally ...
You can also expound more on the rest of the flow control statements to gain more understanding of the subject matter. Finally, in the next section of the Awk series, we shall move intowriting Awk scripts. For those seeking a comprehensive resource, we’ve compiled all theAwkseries articles...
