Example SU Commands

suwind < x.su key=cdp min=100 max=299 | sufilter f=10,20,60,70 | \

sufrac phasefac=-0.75 > xx.su

Backslash at end of line causes pipe to flow from sufilter to sufrac.

suwind<x.su key=ep min=100 max=299|sufilter f=10,20,60,70|sufrac \

phasefac=-0.75>xx.su

Spaces can be omitted except between program names and parameters, but not very readable.
