Re: (somewhat OT:) lilypond calling bash script questions
Thanks all for the generous feedback. But the very simple solution that Jonas Olson posted quite early solved the issue. "for dir in [0-9]*/;" was is exactly what I needed.

Re: (somewhat OT:) lilypond calling bash script questions
A variant of Alex's suggestion (below):
find . -type d -name "[0-9]*" -print | while read dir
do
(
cd $dir;
for f in *.ly
do
lilypond $f
done
)
done
I've typed this directly in my mail client without testing it, so
it's to be expected that some details will need correction.
Sorry about that.

find . -name '*.ly' | while read i; do lilypond "$i"; done
Using read takes care of whitespace.
Or, more compact:
find . -name '*.ly' -exec lilypond '{}' \;

This is guaranteed to fail as soon as any found directory name contains
any sort of whitespace.
[Fun fact: the ONLY characters you can rely on not appearing in a Unix
file name are the forward slash and the null byte.]
It's overkill in this case anyway (see Jonas' or David's replies), but
if you really want to explicitly loop over the output of a find command
call, the proper way to do it is to make it output a list of null-byte
separated strings with the -print0 option and then use an appropriate
shell script construct to loop over this. A solid way to do it in bash
is the following useful idiom:
while IFS= read -r -u3 -d $'\0' FOUND; do
# do what you want with "$FOUND"
...
done 3< <(find [OTHER OPTIONS AS REQUIRED] -print0)

Wow, that's where I had been looking around without success.
However, Jonas' and David's solution doesn't look as geeky but works
perfectly.

I have a project with more than two dozens of lilypond scores. For several
reasons I have them in individual files which I can't \include in a master file.
I would like to write a script that allows me to compile all .ly files in one
run.
For this I need the following which I didn't find through Google:
How can I sequentially cd to all subdirectories that start with a number?
What I want is to do
cd 01_01_...
lilypond *.ly
cd ..
cd 01_02_...
..
in a form like
I only speak Python, but I can help you there
import subprocess
NUMBER_OF_DIRS = 10
for x in range(NUMBER_OF_DIRS) :
subprocess.call("lilypond *.ly", shell=True, cwd="01_"+("%.2d" %
x)+"_foobar")
Note that I haven't tested the above, so I can't guarantee it works and you'd
have to adapt it to your individual case.

Well, I don't speak Python, so I'll hope to get another response.
But from what I can decipher from your script I might have to express
myself clearer:
The condition for the inclusion of a directory is _only_ that it starts
with a number.
The dirs with scores in it are named according to opus number, thus
starting with a two digit number, followed by an underscore and another
two digit number.
But the unique characteristic is that it begins with a number, as all
other directories below the project root start with characters.
Thanks anyway
Urs
