if you use

[Preconditioning
  [./SMP_full]
    type = [SMP](https://mooseframework.inl.gov/source/preconditioners/SingleMatrixPreconditioner.html)

    full = true

    #Preconditioned JFNK (default)
    solve_type = 'PJFNK'
  [../]

then -ksp_view_pmat on the command line will show the jacobian

In addition,could you please tell me where I can find more Petsc command-line parameters? Thank you.

on the petsc manual for sure
