The following example shows how to SHAKE all bond lengths between hydrogens and heavy atoms, and the geometry of all TIP3 water molecules. 

shake
   reference=parameters  molecule ( resname TIP3 ) 
   reference=coordinates  bonds ( hydrogen and not resname TIP3 )   ( all )
   tolerance=1.0e-06
   mxiterations=500
end
