How can I empty the trash from the Terminal? How can I empty the trash from the Terminal?
Another solution would be to create AppleScript containing the folowing code

tell application "Finder"
    empty the trash
end tell


save it as emptytrash for example and execute it via open emptytrash.app

or even better (as suggested by Chris) - execute:

osascript -e 'tell app "Finder" to empty'


Since trash is a Finder thing, this should be more compatible in the long run.
