Personally, I would consider using rename(1) that came with Perl for this, but
you could write a shell script to do the same thing...
find . -type f -print0 | xargs -0 rename \
'my @name = split qr{/};
$name[-1] =~ y/A-Z /a-z_/;
$_ = join("/", @name);'
rename uses an arbitrary Perl expression to mangle $_, which is the input
filename, and the output value is the name to rename it to.
Alternately, in shell, you can do the same, but harder:
find . -type f | while read file; do
dir=$(dirname "$file")
name=$(basename "$file" | tr 'A-Z ' 'a-z_')
test x"$file" = x"$dir/$name" || mv "$file" "$dir/$name"
done
