curl is a great addition to any scripter's arsenal and I tend to use it quite a lot - so I thought I would demonstrate some of its features in this post.

curl -L google.com

Limit download bandwidth (2 MB per second)

curl --limit-rate 2M -O http://speedtest.newark.linode.com/100MB-newark.bin

Perform basic authentication

curl -u username:password https://localhost/restrictedarea

Enabling debug mode

curl -v https://localhost/file.zip

Using a HTTP proxy
