You should read man test and the definition of path, see example:
Code:
$ test -e /test/dir1/foo.bar && echo Path OK || echo Path OK
Path OK                     
$ test -d /test/dir1/foo.bar && echo Path OK || echo Path NOK
Path NOK              #that's wrong , the path exist , however it's not a directory (-d).
