Why -r don't work for me?

[EvagelineFEI]

I tried to use this tool to generate 2200 different sql statements from the template. Mentioned in https://github.com/databricks/tpch-dbgen,- r parameter can be used to specify the seed. However, I run this statement, but the result is the same queries.

for i in seq 22;do ./qgen -d $i -s 1 -r 100 > outputfile/queries/$i.sql; done
