Somehow refactoring turned info rewriting from scratch… So, meet the new shiny mucks app written in AWK language (instead of UNIX Shell). I played with quotes in tmux “send-keys” command, and it turned out that different shells treat quotes in the “read” command very differently, and I found no easy way to overcome it. That’s how AWK came to the rescue. A more mature, yet much simpler language made my code cleaner and shorter.
