bash - 如何在 bash 中使用 mod 运算符？

Question

我正在尝试这样一行:

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

我想得到的输出是:

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

但我实际得到的只是:

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

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 arithmetic evaluation的内容。
