Changes name and host in a terminal to a rickroll after a command.
The first time after cloning, cd into rickroll-lyrics-PS1 and run source setup.sh. Run this only once after cloning the repo.
That should simply setup everything for you.
source roll starts rickroll if not already started. The roll script would have been inserted in '~/.local/bin/' by the setup script.
source roll -r resets everything.
You can also type rick to output a lyric without changing the terminal name or host in a new terminal.
Use rick -r to reset next lyric line index to 0
