Syntax offorloop foriinrange/sequencee: statement1statement2statement n In the syntax,iis the iterating variable, and the range specifies how many times the loop should run. For example, if a list contains 10numbersthen for loop will execute 10 times to print each number. ...
End: The loop repeats this process until the condition becomes false, at which point the loop stops. Examples Of For Loop Program In C++ Now that we have a clear understanding of the syntax and functionality of the for loop in C++, let's look at a few code examples. Example 1: To ...
Python in the second iteration. Go in the third iteration. for loop Syntax for val in sequence: # run this code The for loop iterates over the elements of sequence in order, and in each iteration, the body of the loop is executed. The loop ends after the body of the loop is execute...

可以通过ls -l /bin/*sh命令看到: 所以在使用sh命令执行脚本的时候实际使用的是 dash,而 dash 不支持这种 C 语言格式的 for 循环写法。 解决方法:使用bash代替sh运行脚本: bash test.sh
Another common control flow is a loop. Go uses only one looping construct, and that's aforloop. But you can represent loops in more than one way. In this part, you'll learn about the loop patterns that Go supports. Basic for loop syntax ...

for i in 1 2 3 4; do echo $i; done 2、测试for的自增长的循环: #!/bin/bash for ((i=1; i<=5; i++)) 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。
Bash Until Loop The until statement is very similar in syntax and function to the while statement. The only real difference between the two is that the until statement executes its code block while its conditional expression is false, and the while statement executes its code block while its co...
shell脚本Syntax error: Bad for loop variable 在shell脚本中写for循环出现这个问题 原因: 从 ubuntu 6.10 开始,ubuntu 就将先前默认的bash shell 更换成了dash shell;其表现为 /bin/sh 链接倒了/bin/dash而不是传统的/bin/bash。 解决办法:sudo dpkg-reconfigure dash 选择no 出现如下: 接着运行: 显示成功....
