Ah. It never occurred to me to try to allow for anything but the
standard "lilypond filename.ly" command. That's a good idea. I don't
use anything but the standard command very often, though, so I won't
lose any sleep over it. I *was* prepared to lose sleep over the fact
that the output files weren't ending up in the right directory ;-) Glad
to have figured that one out.
I didn't even know the basename command until today when I started
researching the problem. I have a book to thank for that. The book and
the manpage for basename both mention the extension-chopping function.
Very useful. I was using a sed command to do that before, but I like
basename better b/c I didn't really understand what sed was doing, I
just copied and slightly tweaked someone else's line of code in another
script (sort of like what we do with lilypond snippets, I guess). The
advantage of sed over basename for this, though, is that sed doesn't
require you to specify exactly what the extension is that you want to
chop off. I tried using "basename ~/Documents/filename.ly .*" and it
returned errors. You have to tell it exactly what extension you want to
extract: "basename ~/Documents/filename.ly .ly" returns "filename".
This is fine for a script designed specifically for lilypond, but it
would be more flexible if it allowed for a wildcard that would chop off
whatever extension happened to be there.
The book is "Beginning Shell Scripting," by Eric Foster-Johnson, John
Welch, and Micah Anderson. I also have "Classic Shell Scripting," an
O'Reilly book, but I find that Beginning Shell Scripting is better about
explaining every detail of every example, which is important for me
since I'm such a newb :).
Thanks for writing the script, Jay. I'm going to study and break it
down bit by bit to see what I can learn from it. It works great!

The scripts do essentially the same thing. The only thing I was trying
to do was allow for normal lilypond command line arguments also. The
sed line is a hack to pull out all but the last argument. It will
break if the last argument is quoted and has a space in it.

P.S. I didn't know basename took a second argument to chop off the
extension. Neat.
