The command yt-dlp --list-formats "${https:--www-youtube-com-watch?v=oHg5SJYRHA0}" is used to fetch and display the available video and audio formats for a YouTube video. Let's break down the command:

• yt-dlp: It refers to a command-line tool used for downloading videos from various websites, including YouTube. Similar to its predecessor youtube-dl, yt-dlp provides additional features and bug fixes.

• --list-formats: This flag tells yt-dlp to list the available formats for the given video URL instead of actually downloading the video. It is useful when you want to check the available formats before downloading.

• "${https:--www-youtube-com-watch?v=oHg5SJYRHA0}": This part of the command is the URL of the YouTube video you want to fetch the formats for. In this example, the video URL is https://www.youtube.com/watch?v=oHg5SJYRHA0, which is a famous Rickroll video. The URL is enclosed within quotes and preceded by "${https:--www-youtube-com-watch?v=oHg5SJYRHA0}" syntax, which may not be necessary depending on the command execution context.

By running the command, the yt-dlp tool will connect to YouTube, analyze the provided video URL, and display a list of available formats with their respective quality specifications such as resolution, format type, and bitrate. It will assist in selecting the desired format for downloading the video if necessary.
