Getargv is a gem that allows you to query the arguments of other processes as an array or string. This gem only supports macOS because the KERN_PROCARGS2 sysctl only exists in xnu kernels, BSD or Linux users should just read /proc/$PID/cmdline which is much easier and faster, Solaris users should use pargs. This gem requires you have [libgetargv](https://getargv.narzt.cam/) installed. To limit the getargv gem to Apple OSs add it to your Gemfile like so: gem "getargv", "~> 0.3.12", platforms: :ruby, install_if: RbConfig::CONFIG["host_os"].include?("darwin")
