Unix - Loop Control

Loop control in UNIX is used to control the execution of loops, which are used to iterate over a block of code until a certain condition is met. There are three types of loop control statements in UNIX:

break: This statement is used to terminate the loop and exit the loop entirely. It is usually used in conjunction with an if statement to check for a certain condition that warrants ending the loop.

continue: This statement is used to skip over the current iteration of the loop and proceed with the next iteration. It is usually used in conjunction with an if statement to skip over certain iterations that do not meet a certain condition.

exit: This statement is used to exit the current shell or script entirely. It is not specific to loops, but can be used in conjunction with loops to exit the script if a certain condition is met.

These loop control statements are used to make the code more efficient and reduce the amount of code that needs to be written. They are also used to make the code more readable and easier to understand.
