How to use mod operator in bash?

Question

I'm trying a line like this:

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

What I'm trying to get as output is:

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 

But what I'm actually getting is just:

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

Answer 1

Try the following:

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

The $(( )) syntax does an arithmetic evaluation of the contents.
