cURL - client for URLs

Have been hearing about the tool cURL but never looked into its expansion - its client for URL!

Yes, it deals with URL and hence can also be called as "see URL"

cURL Commands in action:

2. Save the output of an URL to a file

this command saves the output of the site page to the file named website in the current working directory

• -o (lowercase o) the result will be saved in the filename provided in the command line
• -O (uppercase O) the filename in the URL will be taken and it will be used as the filename to store the result
