我试着这样一行：
for i in {1..600}; do wget http://mydomain.com/search/link $i % 5; done;
我想得到的输出是：
wget http://mydomain.com/search/link0 wget http://mydomain.com/search/link1 wget http://mydomain.com/search/link2 wget http://mydomain.com/search/link3 wget http://mydomain.com/search/link4 wget http://mydomain.com/search/link0
但我实际得到的只是：
wget http://mydomain.com/search/link
尝试以下操作：

$(())语法做一个arithmetic evaluation的内容。
