after editing a script using vi i get a copy of the script ending in ~

why?

hi,

i bet this is a doh! question but am finding impossible to track the answer down :-)

sometimes when i exit a file in vi a copy of the same file is left but with ~ on the end. this only happens sometimes?

any clues?

cheers

It's the backup.

Google for "tilde files" vi.
