  The present work deals with dynamics of gravitational collapse with
cylindrical symmetry as developed by Misner and Sharp. The interior collapsing
anisotropic cylindrical perfect fluid is matched to an exterior vacuum
cylindrically symmetric space-time due to Einstein--Rosen using the Darmois
matching conditions. It is found that the radial pressure of the anisotropic
perfect fluid is non-zero on the boundary surface and is related to the
components of shear viscosity. As a result, there is formation of gravitational
waves outside the collapsing matter.
