Subject: Getting pipe return codes from SYSTEM command

I'm trying to find the return codes from bash for piped commands. i.e.

system("ls")

puts("#{$?.exitstatus}")

This returns the return code of ls

system("ls |  bzip2 -c > ./out.txt")

how can I still get the return code of ls?

Thanks,

Russell.
