NOTE: This is a question I found on StackOverflow which I’ve archived here, because the answer is so effing phenomenal.

If you are not into long explanations, see [Paolo Bergantino’s answer][2].

    this.setIndex = false;
    this.useNew = false;
    for (var i = 0; i < arguments.length; ++i) {
      var arg = arguments [i];

    tmux is a "terminal multiplexer", it enables a number of terminals to be accessed and controlled from a single terminal.
    
  If you use Debian/Ubuntu, you can just run apt-get install tmux, and voila. 
  
  Since the title was about centos 7, then do the following step to install tmux.
  
  (1). tmux has a library dependency on libevent which, of course, isn’t installed by default. 
    $ wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
    $ tar xzvf libevent-2.0.21-stable.tar.gz
    $ cd libevent-2.0.21-stable
