Lesson 5 Revise, Answers of the Questions

Today we'll make a revision of the previous lessons answering the questions of lesson 4.
Here are the questions:

1. Why have we used '&' after audacious -e "$music"? What does it means? try to open other programs with '&' at the end and without it!
2. Why we put the audacious -e "$music" & in the for loop and didn't used a playlist variable like before? What script is better?
3. Why music variable has a '$' in the for loop?
4. Why have we put *.wma instead of *.mp3? Are you going to do the same?
5. Why the -E became a -e? Check man audacious to find out!

1. & runs the command or program in background, so the terminal is free for putting other commands!
2. Because the -e adds songs to the current playlist.
3. If a variable is going to be used for output must have $ in front
4. The songs of Celine Dion was in wma format. If yours are mp3 or other format you shouldn't use wma.
5. Because -E creates a temporary playlist.
