The VI text editor is a very flexible text editor. This can read from STDIN, and this makes it very good to use in a script. But you can also read a file from the Internet. This works in concert with the wget utility.
The wget -O- -q command reads a file from the Internet and prints it to STDOUT. Then the vi - command reads the file into the text editor.

This works very well indeed. Use the :q! VIM command to exit. The :w playlist.txt VIM command will write a copy of the file into the playlist.txt file.
