This is the easiest and most concise way of calling an external process in Java. The inheritIO methods causes the command to output stdout and errout to the same place as your current process (which most of the times is the console), no need to create mechanisms for reading asynchronously from input streams to get at the information.

(def ret (.waitFor (-> (ProcessBuilder. ["gzip" "-t" "g.txt.gz"]) .inheritIO .start)))
