Curl

Curl Syntax :

    curl [options] [URL...]

• -I or --head - To make head request for url.

Fetch the HTTP-header only! HTTP-servers feature the command HEAD which this uses to get nothing but the header of a document. When used on a FTP or FILE file, curl displays the file size and last modification time only

• -L or --location - To follow redirect.

• -I or --silent - To avoid lots of output, this displays just the critical output.
