I like htop interactive process viewer. Recently I found another one called gtop. It is similar to top, but fancier. Let us see how to install and use gtop on a Linux or macOS Unix based system.
Installation
First you need to install npm using apt command/apt-get command on an Ubuntu or Debian based system:
$ sudo apt install npm nodejs

A note about CentOS/RHEL 7 users
If you are using a RHEL/CentOS Linux 7, first install a package named epel-release and followed by nodejs and npm using the yum command:
# yum install epel-release
# yum install nodejs npm
A note about Fedora Linux users
If you are using a Fedora Linux, install nodejs and npm using the dnf command:
$ sudo dnf install epel-release
$ sudo dnf yum install nodejs npm
A note about macOS Unix users
Type the following brew command:
$ brew install node
Installing gtop
To install gtop, type the following command:
npm install gtop -g

Usage
Simply type the following command:
gtop
OR
nodejs /usr/local/bin/gtop
Sample outputs:
You can sort the process table by pressing the following keys:
- Press p to sort by process ID (PID).
- Press c to sort by CPU usage.
- Press m to sort by memory usage.
Even though gtop is pretty fancy. I recommend htop tool or atop utility or top command only for server usage.
