I want to set environment variable from script in Bitrise. for example I am setting build version based on date like 03.16 and build number start from 1. once date change from ex 17th march than build version will change to 03.17 and build number start from 1 again. I have script to set build version and build number. I can generate build version from shell command but I have to store build number. every build trigger in same date build number will increase by one

for example first build on 16th march version would be 03.16(1) second build on 16th march version would be 03.16(2) . . first build on 17th march version would be 03.17(1) second build on 17th march version would be 03.17(2)
