How to install Htop 2.0.2 on Ubuntu 16.04

   Htop is an interactive real time process monitoring application for Linux/Unix like systems and also a handy alternative to top command, which is default process monitoring tool that comes with pre-installed on all Linux operating systems

     Since version 2.0, htop is now cross-platform! Check out the video and slides of my presentation at FOSDEM 2016 about how this came to be. This release includes code supporting Linux, FreeBSD, OpenBSD and Mac OS X.

There are also, of course, some new features:
  •     If you're using NCurses 6, htop will also support your mouse wheel for scrolling.
  •     Moving meters and columns around in the setup screen is a lot more comfortable now.
  •     You can now press "e" to see the set of environment variables for a process.
  •     The "graph" mode for meters was revamped, inspired by James Hall's vtop.
htop 2.0.2 changelog: 

  •     Mac OS X: stop trying when task_for_pid fails for a process, stops spamming logs with errors.
  •     Add Ctrl+A and Ctrl+E to go to beginning and end of line
  •     FreeBSD: fixes for CPU calculation
  •     Usability: auto-follow process after a search.
  •     Use Linux backend on GNU Hurd
  •     Improvement for reproducible builds.
  •     BUGFIX: Fix behavior of Alt-key combinations
  •     Various code tweaks and cleanups
