Why is wget saving something when using parametrized url?

Question

I am using following command in my bash script to trigger jenkins build:

wget --no-check-certificate "http://<jenkins_url>/view/some_view/job/some_prj/buildWithParameters?token=xxx"

Output:

HTTP request sent, awaiting response... 201 Created
Length: 0
Saving to: “buildWithParameters?token=xxx”

[ <=>                                                                                                                                                                       ] 0           --.-K/s   in 0s      

2015-02-20 10:10:46 (0.00 B/s) - “buildWithParameters?token=xxx” saved [0/0]

And then it's creates empty file: “buildWithParameters?token=xxx”

My question is: why wget creates this file and how to turn that functionality off?

Answer 1

Most simply:

wget --no-check-certificate -O /dev/null http://foo

this will make wget save the file to /dev/null , effectively discarding it.
