'\' is used for telling shell to remove the special features associated with a character.

For eg: %s/search/replace/g

Here '/' is used to separate the pattern to be searched and pattern to be replaced.
But if you have '/' in the pattern to be searched, you have to dereference it like below.

%s/\/export/\/import/g

This will replace /export with /import. So I used '\' to remove the special feature of '/'.
