在Bash For Loop中使用’break’ 语句 顾名思义, “break”语句会在满足条件时停止或结束迭代,考虑下面的For循环。 #!/bin/bash for n in {1..10} do if [[ $n -eq '6' ]] then echo "Target $n has been reached" break fi echo $n done echo "All done" 这是代码的作用: 第2行:标记for...
【break命令的使用】在bash shell中，break命令用于立即终止当前循环的执行。例如，以下是一个使用break命令的for循环示例：#break out of a for loopfor var in {1..9}do echo "The next number is $var" if [ $var -eq 5 ] then break fidone 在这个示例中，当变量var的值为5时，整个循环...
In the for loop, we can use the break statement to stop its execution and get control back to the for loop. You can see the loop prints only the first 3 values and when it reached 3 then due to the break statement it stops execution. for ((i = 0 ; i <= 5 ; i++)); do i...

$ bash forloop1.sh Example 2 - for Loop With a Break Statement The break statement is used within the ‘for loop’ to end the loop. First, create a file and run the following code. For instance, we will use for loop to read the list of names, and we will test two conditions....
循环是代码中很常用的情况。 针对于循环: return 、break 、continue 都是退出循环。 return 是退出整个循环体及其之后的代码,不管是循环内还是循环外的代码。 break 是退出整个循环体,之后的都不会再循环。 continue 是退出本次循环,后面符合条件的依然会继续循环。 ... ...
Example 6 - Break, Continue statement usage There are two bash built-in keywords that are used to control the flow of your loops. Break- Exits the loop and skip any pending iterations. Continue- Skip the current iteration and pass the control back to the for loop to execute the next iter...

Bash “For” Loop Break You can implement a Bash “for” loop that breaks when a given condition is met. For instance, let’s say you want to loop through a list of files and only break when a given condition is met. The Bash “for” loop only breaks if the condition in the “if...
for循环 While 循环 Until 循环可以嵌套。与任何其他编程语言一样,bash 也支持 break 语句退出当前循环,并支持 continue 语句恢复循环语句的下一次迭代。 Bash For 循环 – 第一种方法 当在进入 bash 循环之前知道迭代次数时,通常使用 for 循环。Bash 支持两种 for 循环。bash for 循环的第一种形式是: ...
