Gabriel Arazas 377850d0d1 Update notebook and clean up the folder 
I also forget to add the additional solutions from the Exercism
exercises. Whoops...

I'm also getting used to storing code in random places. Time to change
that habit a little bit by storing them in my notebook, instead.
Nothing wrong with that, yeah?!

Command line: cURL

The all-time favorite client-side networking tool for basic stuff. It is seriously one of the best free and open-source tool out there with the plethora of protocols, leading implementation for various protocols such as HTTP3, and a lot of configurable options to fully control your request.

Synopsis 

curl [option...] [URL...]

cURL supports creating requests with different protocols. Among them are HTTP, Gopher, DICT, and simple file. To see more, you can view the cURL manual page (i.e., man curl.1) and see the protocols section.

Options

  • -o [FILE], --output [FILE] - save the results in the given file
  • -O, --remote-name - save the results as the remote name; useful for downloading
  • -L, --location - if there redirects, follow them; mainly used in HTTP

Examples

This is a massive tool with a massive history so a massive list may be justified for this one.

Basic usage 

# It will be recognized as a request to an HTTP endpoint in 'gnu.org'.
curl https://gnu.org

# Save the result in a file.
curl https://foo-dogsquared.github.io --output filename

Go-to command for downloading files with cURL 

curl -LO https://cdn.media.ccc.de/events/lac/lac18/h264-hd/lac18-24-eng-Carla_Plugin_Host_-_Feature_overview_and_workflows_hd.mp4

It can be also written like the following code block. Useful when scripting to make it readable.

curl --location --output-name https://cdn.media.ccc.de/events/lac/lac18/h264-hd/lac18-24-eng-Carla_Plugin_Host_-_Feature_overview_and_workflows_hd.mp4
