OS X 10.6 services - how to force reindexing

Question

I have an application installed on OS X 10.6 which offers some services when a file or directory is selected in the Finder. After moving the application to trash, the service entries are still shown in the Finder.

How to force OS X to "reindex" the known services?

Answer 1

Run pbs (the paste board server) to reset it:

$ /System/Library/CoreServices/pbs

see this Apple documentation.

Or, empty the trash.
