Compile and Install Htop from Source Packages

To install Htop 2.0.2 version, you must have Development Tools and Ncurses installed on your system, to do so run the following series of commands on your respective distributions.

On RHEL/CentOS and Fedora

# yum groupinstall "Development Tools"
# yum install ncurses ncurses-devel
# wget https://hisham.hm/htop/releases/2.0.2/htop-2.0.2.tar.gz
# tar xvfvz htop-2.0.2.tar.gz
# cd htop-2.0.2

On Debian and Ubuntu

$ sudo apt-get install build-essential  
$ sudo apt-get install libncurses5-dev libncursesw5-dev
$ wget https://hisham.hm/htop/releases/2.0.2/htop-2.0.2.tar.gz
$ tar xvfvz htop-2.0.2.tar.gz
$ cd htop-2.0.2

Next, run the configure and make script to install and compile htop.

# ./configure
# make
# make install

How do I use htop?

Now run the htop monitoring tool by executing following command on the terminal.

# htop

Htop is having three sections mainly

  1. Header, where we can see info like CPUMemorySwap and also shows tasks, load average and Up-time.
  2. List of processes sorted by CPU utilization.
  3. Footer shows different options like helpsetupfilter tree killnice , quit etc.

Press F2 or S for setup menu > there are four columns i.e SetupLeft ColumnRight Column and Available Meters.

Here, you can configure the meters printed at the top of the window, set various display options, select among color patterns and choose which columns are printed in which order.

Type tree or t to display processes tree view.

You can refer function keys displayed at footer to use this nifty htop application to monitor Linux running processes. However, we advise to use character keys or shortcut keys instead of function keys as it may have mapped with some other functions during secure connection.
