Shell Programming and Scripting

AUDIOPATH=$PLAYLIST/MP3

You tell it. Presumably, "$AUDIOPATH" contains the directory with the mp3s. If not, why did you assign it?

You tell it. That's what the variable is for.

I didn't; you did.

You had:

Code:

AUDIOPATH='/home/Fedora11/MP3'

That is the same thing as:

Code:

AUDIOPATH=$PLAYLIST/MP3

I wish you'd post the parts of the script that are giving you problems and tell us exactly what the problem is; then maybe we could be of more help.

What command from what variable?

I suggest that you create a separate function for each of the various actions the user may select.

Code:

## Functions for each task
create_playlist() { 
  : put appropriate commands here
}

edit_playlist() { 
  : put appropriate commands here
}

delete_playlist() { 
  : put appropriate commands here
}

generate_playlist() { 
  : put appropriate commands here
}

play_mp3() { 
  : put appropriate commands here
}

copy_mp3() { 
  : put appropriate commands here
}

delete_mp3() { 
  : put appropriate commands here
}

## Print menu and execute user's selection
while  :
do
  printf %s '
