htop process monitor

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

Comparison between htop and top :-

• In 'htop' you can scroll the list vertically and horizontally to see all processes and complete command lines.

• In 'top' you are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident).

• 'htop' starts faster ('top' seems to collect data for a while before displaying anything).

• In 'htop' you don't need to type the process number to kill a process, in 'top' you do.

• In 'htop' you don't need to type the process number or the priority value to renice a process, in 'top' you do.

• 'htop' supports mouse operation, 'top' doesn't

• 'top' is older, hence, more used and tested.
