A previous post talked about the usage of
curl to request a single URL and display its response header fields. It’s good to know that
curl also accepts multiple URLs as arguments.
To display response header information of several URLs:
curl -I http://linuxbyexample.co.nr http://lne.blogdns.com/lbe
When there is a long URL list in a file, use
xargs curl -I < url-list.txt
