i find sed handy for this kind of batch text manipulation
you have to escape the \ in \transpose so it is written \\transpose
you also have to do a bit of uglyness to escape the ' so ' will
become \'\''
this oneliner will replace \transpose c' d' with \transpose c' b' in
all the files in whatever directory you execute it in
sed s'/\\transpose c\'\'' d\'\'' /\\transpose c\'\'' b\'\''/'g *.ly
this will spit the output into the terminal for you to check then when
you are sure it is good you can add the -i flag to make it actually edit
the files
sed -i s'/\\transpose c\'\'' d\'\'' /\\transpose c\'\'' b\'\''/'g *.ly

Here is one I just thought of... (Haven't tested yet) It should make copies
transposed for clarinet.
$line=~s:\\relative c':\\transpose c b \\relative c':;
$line=~s:\\chordmode:\\transpose c b \ \chordmode:;
$line=~s:Violin:Clarinet:;

I had a bunch of band charts I needed to update. I wanted to assign each
chart a number and give them all a midi tempo. Then every now and then I
learn something new that I want to add.
I dusted off an old Perl script, changed a few lines and I was able to
automate the process. It reads all the lilypond files in a folder, reads
and changes the text inside and writes the updated file to a temporary
folder called "changed". Open to the changed folder in a terminal, type
"lilypond *" and lily will recompile everything.
The key to the whole thing is the line=~s/xxx /yyy / lines. If you have
ever used regex it will make sense.
open(OUT, ">changed/$file"); #output is to a folder called "Changed" one
level deeper in tree
foreach my $line(@text){
$line=~s:\\date:\\italic{ \"Sheet $cnt | Updated
\" \\date } :;
$line=~s:\\midi { }:$midistring:;
print OUT $line;
}
This is the whole program. http://old.nabble.com/file/p30495491/lymod.pl
