bash - Some questions of automate the process of iOS builds -

recently,i try automate process of ios builds using bash scripts.

i'm building app,code signing file using xcodebuild, , pack project using xcrun. in xcode,we can set information easily,(summary->ios application target->...)

but,how can set information without xcode,i want using bash scripts,like modify info-plist or other configuration files,does works? how can solve question?

the second question:

because want automate ios builds in server, need import certificates(.p12) clients give me keychain automatically,the question how can export .p12 file automatically keychain when clients give me name of code signing.

can provide me information of automating process of ios builds using bash scripts？ or have realize function? please give me clues that, or program.

you can inject custom build settings passing key=value arguments xcodebuild. can put these info.plist values ${my_build_setting}.
