Spotify - Shell-Bash

Introduction

Spotify is a popular music streaming service that offers millions of songs for users to listen to. Shell-Bash is a command-line interface that allows users to interact with Spotify directly from their terminal.

In this guide, we will cover how to authenticate with Spotify, search for songs, create and manage playlists, play songs, and control the player's playback.

Authentication

Before using Spotify's API, you need to authenticate your application. To authenticate your Shell-Bash application, you will need a client ID and a client secret.

To register your application with Spotify, visit the dashboard. Once registered, you can access your client ID and client secret.

To authenticate your application using Shell-Bash, you can use the following command:

$ curl -X "POST" -H "Authorization: Basic {base64 encoded client ID:client secret}" -d grant_type=client_credentials https://accounts.spotify.com/api/token

This will return an access token that you can use for subsequent requests.

Searching for Songs

You can search for songs using the following command:

$ curl -X "GET" -H "Authorization: Bearer {access token}" "https://api.spotify.com/v1/search?q={query}&type=track&limit={limit}"

Replace {access token} with the access token obtained from authentication. Replace {query} with the search term and {limit} with the number of results you want to retrieve.

This will return a JSON object containing the search results.

Creating and Managing Playlists

You can create a new playlist using the following command:

$ curl -X "POST" -H "Authorization: Bearer {access token}" -H "Content-Type: application/json" -d '{"name":"{playlist name}", "description":"{playlist description}", "public":false}' "https://api.spotify.com/v1/users/{user ID}/playlists"

Replace {access token} with the access token obtained from authentication. Replace {playlist name} and {playlist description} with the name and description of your new playlist. Replace {user ID} with your Spotify user ID.

This will create a new playlist and return a JSON object containing the playlist information, including its ID.

You can add songs to a playlist using the following command:

$ curl -X "POST" -H "Authorization: Bearer {access token}" -H "Content-Type: application/json" -d '{"uris":["spotify:track:{track ID}", "spotify:track:{track ID}"]}' "https://api.spotify.com/v1/playlists/{playlist ID}/tracks"

Replace {access token} with the access token obtained from authentication. Replace {track ID} with the Spotify track ID of the track you want to add to your playlist. Replace {playlist ID} with the ID of the playlist you want to add the track to.

You can also remove songs from a playlist using the following command:

$ curl -X "DELETE" -H "Authorization: Bearer {access token}" "https://api.spotify.com/v1/playlists/{playlist ID}/tracks" -d '{"tracks":[{"uri":"spotify:track:{track ID}"}]}'

Replace {access token} with the access token obtained from authentication. Replace {playlist ID} with the ID of the playlist you want to remove the track from. Replace {track ID} with the Spotify track ID of the track you want to remove.

Playing Songs

You can play songs using the following command:

$ curl -X "PUT" -H "Authorization: Bearer {access token}" -H "Content-Type: application/json" -d '{"uris":["spotify:track:{track ID}"]}' "https://api.spotify.com/v1/me/player/play"

Replace {access token} with the access token obtained from authentication. Replace {track ID} with the Spotify track ID of the track you want to play.

Controlling the Playback

You can control the playback using the following commands:

• Play: $ curl -X "PUT" -H "Authorization: Bearer {access token}" "https://api.spotify.com/v1/me/player/play"
• Pause: $ curl -X "PUT" -H "Authorization: Bearer {access token}" "https://api.spotify.com/v1/me/player/pause"
• Skip to next track: $ curl -X "POST" -H "Authorization: Bearer {access token}" "https://api.spotify.com/v1/me/player/next"
• Skip to previous track: $ curl -X "POST" -H "Authorization: Bearer {access token}" "https://api.spotify.com/v1/me/player/previous"
• Set volume: $ curl -X "PUT" -H "Authorization: Bearer {access token}" "https://api.spotify.com/v1/me/player/volume?volume_percent={volume percent}"

Replace {access token} with the access token obtained from authentication. Replace {volume percent} with the percentage of volume you want to set (0-100).

Conclusion

With Shell-Bash and Spotify, you can easily interact with Spotify's API directly from your terminal. By following the above commands, you can authenticate, search for songs, create and manage playlists, play songs, and control the player's playback.
