knowing the package providing a program

[Willy Hamra]

hi, if i have a certain program, how can i know what package is
providing this program by giving it's absolute path? i have 2
executables with the same name in 2 different directories both in
PATH. one is provided by a 3rd party deb package, the other coming
from the ubuntu repositories. how can i know which is which?
