About Trash setting

Hi,

I have 2 questions about trash setting, thanks.

1. How to get the real path of trash? I found it should be ~/.Trash, but the path can not added to automate.
2. Is there parameter which can be used to delete directly, not to trash folder.

find / -name .DS_Store -exec rm {} + 
find . -name .DS_Store -type f -delete
