title: Linux: list all available window managers
body: <p>How do I get a list of all available windows managers on a linux system (Of course this would mostly not be needed but - I don't have root permissions).
    Very difficult to search on Google as all results returned are for "list of window managers for linux".</p>
  
  <p>Clarification:  I am looking for a command that lists "All window managers that are installed" on the system that I am working on.</p>
  
  <p>Interested to know it's distro dependent. My distro is RedHat.</p>
