Loop Control: next, last, redo, continue
Explore Perl's loop control statements including next, last, redo, and continue to efficiently control iteration flow in loops. Learn to use these statements to skip iterations, end loops early, restart iterations without re-evaluating conditions, and run code after each iteration. This lesson helps you write more readable and maintainable Perl loops, including handling nested loops with labels.
We'll cover the following...
Sometimes, we must break out a loop before we’ve exhausted the iteration conditions. Perl’s standard control mechanisms (exceptions and return) work, but we can also use loop control statements.
The next statement
The next statement restarts the loop at its next iteration. Use it when we’ve done everything we need to do in the current iteration. To loop over lines in a file, skipping those that start with the ...
