Explanation Firstly the function checks if user gave it any input, and notifies the user if they failed to do so. If user has inputed a search string, the function will call upon youtube-dl to find url of the audio of the first matching youtube video and play that with mpv. Call function by wrapping search string in quotes: listen-to-yt "sultans of swing" You have to paste the line in your .zshrc and source .zshrc for it to work. Limitations The dependancies are youtube-dl and mpv. this oneliner is stolen from http://www.bashoneliners.com/oneliners/302/
1listen-to-yt() { if [[ -z "$1" ]]; then echo "Enter a search string!"; else mpv "$(youtube-dl --default-search 'ytsearch1:' \"$1\" --get-url | tail -1)"; fi } -
