如何在bash中使用mod运算符? [英] How to use mod operator in bash?

问题描述

我正在尝试这样的一行:

I'm trying a line like this:

for i in {1..600}; do wget http://example.com/search/link $i % 5; done;

我想要得到的输出是:

wget http://example.com/search/link0
wget http://example.com/search/link1
wget http://example.com/search/link2
wget http://example.com/search/link3
wget http://example.com/search/link4
wget http://example.com/search/link0

但是我实际上得到的只是:

But what I'm actually getting is just:

    wget http://example.com/search/link

推荐答案

尝试以下操作:

 for i in {1..600}; do echo wget http://example.com/search/link$(($i % 5)); done

$(( ))语法执行算术评估内容.
