== Getargv 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 <code>/proc/$PID/cmdline</code> 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", "~> 0.3.21", platforms: :ruby, install_if: RbConfig::CONFIG["host_os"].include?("darwin")
