This is the shortest script for processing the tutorial data with DIALS assuming you have the data in a parent directory:
dials.import ../xtal_1_5_master.h5
dials.find_spots imported.expt
dials.index imported.expt strong.refl
dials.refine indexed.expt indexed.refl
dials.integrate refined.expt refined.refl
dials.symmetry integrated.expt integrated.refl
dials.scale symmetrized.expt symmetrized.refl
If you run this before working through the tutorial you can spend the time looking at the log files (e.g. cat dials.find_spots.log) rather than waiting for the individual tasks to complete.
