Loops allow you to run one or more commands multiple times until a certain condition is met. In Bash, break and continue statements allows you to control the loop execution.
Loops allow you to run one or more commands multiple times until a certain condition is met. However, sometimes you may need to alter the flow of the loop and terminate the loop or only the current iteration.
continue statements allows you to control the loop execution.
break statement terminates the current loop and passes program control to the command that follows the terminated loop. It is used to exit from a
select loop. s The syntax of the
break statement takes the following form:
[n] is an optional argument and must be greater than or equal to 1. When
[n] is provided, the n-th enclosing loop is exited.
break 1 is equivalent to
To better understand how to use the
break statement, let’s take a look at the following examples.
In the script below, the execution of the
[while](https://linuxize.com/post/bash-while-loop/) loop will be interrupted once the current iterated item is equal to
i=0 while [[ $i -lt 5 ]] do echo "Number: $i" ((i++)) if [[ $i -eq 2 ]]; then break fi done echo 'All Done!'
Number: 0 Number: 1 All Done!
Java continue statement can be used in any of the loop structures. It causes a loop to jump to the next iteration of the loop immediately.
Break Statement in C++ Example | C++ Break Statement Program. The break statement is used to terminate the loop. We can use with switch, for and while loop.
In this tutorial, we will walk you through the basics of the Bash if statement and show you how to use it in your shell scripts. Decision making is one of the most fundamental concepts of computer programming. Like in any other programming language, if, if..else, if..elif..else and nested if statements in Bash can be used to execute code based on a certain condition.
In this tutorial, we will cover the basics of the select construct in Bash. The select construct generates a menu from a list of items. It has almost the same syntax as for loop.If the user enters a number that corresponds to the number of one of the displayed items, then the value of [ITEM] is set to that item. The value of the selected item is stored in the variable REPLY. Otherwise, if the user input is empty, the prompt and the menu list are displayed again.
