I tried v.generalize on the Province_general3 shapefile on Linux with
type=boundary method=douglas threshold=100000 and it did not modify
any boundaries. I also tried the input province shapefile and get the
same output. That is, if Province_general3 has been generated on
windows, I do get the same result on Linux, no difference between the
OS's. Are you using an older grass version on Linux?
