Query: Measurements and implications of cosmic ray anisotropies from TeV to
  trans-EeV energies   Important observational results have been recently reported on the angular
distributions of cosmic rays at all energies, calling into question the
perception of cosmic rays a decade ago. These results together with their
in-progress interpretations are summarised in this review paper, covering both
large-scale and small-scale anisotropies from TeV energies to the highest ones.
While the magnetic field in the Galaxy has long been considered as an external
data imprinting a quasi-random walk to particles and thus shaping the angular
distributions of Galactic cosmic rays through the induced average density
gradient, the information encompassed in the angular distributions in the
TeV--PeV energy range appear today as a promising tool to infer some properties
of the local magnetic field environments. At the highest energies, the
extragalactic origin of the particles has been recently determined
observationally. While no discrete source of ultrahigh-energy cosmic rays has
been identified so far, the noose is tightening around nearby extragalactic
objects, and some prospects are discussed.
