As we can see in the first, do-while loop syntax, the 'condition' is checked as the first statement. This means if the condition is false, the do-while loop in syntax 1 will not perform any iterations. Whereas in the second syntax, the 'condition' is checked as the last statement in...
For loop: It allows users to execute a block of code a specific number of times. While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to execute a block of code at least once and then repeatedly execute it if a ...

In this final chapter on flow control, we will look at another of the shell’s looping constructs.The for loop differs from the while and until loops in that it providesa means of processing sequences during a loop. This turns out to be very useful when programming.Accordingly, the for ...

do echo $i; done 如果会报错,没有则跳过: Syntax error: Bad for loop variable 原因:代码对于标准bash而言没有错,因为Ubuntu为了加快开机速度,用dash代替了传统的bash,是dash在捣鬼。 解决方法:取消dash dpkg-reconfigure dash 出现弹框,选择NO 参考原文详情,解决报错: ...
In such cases, use a while loop. Fixed number of times: Print the multiplication table of 2. In this case, you know how many iterations you need. Here you need 10 iterations. In such a case use for loop. for loop in Python Syntax of for loop for i in range/sequencee: statement ...
