htop is just like top, but on steroids.
Once you are used to htop, you’ll never go back to top again.
htop is a ncurses-based process viewer…..
Install Htop :-
# apt-get install htop / # yum install htop
or
Source download Htop
tar xvfz htop-0.9.tar.gz
cd htop-0.9
./configure
make
make install
#htop
