Remove ._*- and .AppleDouble-files from folders.
Adapted from Torkel's comment on http://hints.macworld.com/article.php?story=20021118060850652
Cred to hiber for suggesting adding -print0/-0 to solve whitespace issue.

See all ._*-files:
find . -name '._*' | more

Remove all ._*-files:
find . -name '._*' -print0 | xargs -0 rm

See all .AppleDouble-files:
find . -name '.AppleDouble' | more

Remove all .AppleDouble-files:
find . -name '.AppleDouble' -print0 | xargs -0 rm -rf

Remove all Thumbs.db-files:
find . -name 'Thumbs.db' -print0 | xargs -0 rm

you can also delete files directly with find using the -delete flag:

find . -name '._*' -delete
find . -name '.DS_Store' -delete
find . -name 'Thumbs.db' -delete

this has the benefit of handling the entire operation using just find (without spawning any child processes), and should be the most performant method in this thread.
