|
|||
|
|
======
|
|||
|
|
|
|||
|
|
|
|||
|
|
You already know about “top” command, don’t you? Yes, It provides dynamic real-time information about running processes in any Unix-like operating systems. A few developers have built graphical front-ends for top command, so the users can easily find out their system’s activity in a graphical window. One of them is **Gotop**. As the name implies, Gotop is a TUI graphical activity monitor, written in **Go** language. It is completely free, open source and inspired by [gtop][1] and [vtop][2] programs.
|
|||
|
|
|
|||
|
|
In this brief guide, we are going to discuss how to install and use Gotop program to monitor a Linux system’s activity.
|
|||
|
|
|
|||
|
|
### Installing Gotop
|
|||
|
|
|
|||
|
|
Gotop is written using Go, so we need to install it first. To install Go programming language in Linux, refer the following guide.
|
|||
|
|
|
|||
|
|
After installing Go, download the latest Gotop binary using the following command.
|
|||
|
|
```
|
|||
|
|
$ sh -c "$(curl https://raw.githubusercontent.com/cjbassi/gotop/master/download.sh)"
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
And, then move the downloaded binary to your $PATH, for example **/usr/local/bin/**.
|
|||
|
|
```
|
|||
|
|
$ cp gotop /usr/local/bin
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Finally, make it executable using command:
|
|||
|
|
```
|
|||
|
|
$ chmod +x /usr/local/bin/gotop
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
If you’re using Arch-based systems, Gotop is available in **AUR** , so you can install it using any AUR helper programs.
|
|||
|
|
|
|||
|
|
Using [**Cower**][3]:
|
|||
|
|
```
|
|||
|
|
$ cower -S gotop
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Using [**Pacaur**][4]:
|
|||
|
|
```
|
|||
|
|
$ pacaur -S gotop
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Using [**Packer**][5]:
|
|||
|
|
```
|
|||
|
|
$ packer -S gotop
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Using [**Trizen**][6]:

|||
|
|
$ trizen -S gotop
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Using [**Yay**][7]:
|
|||
|
|
```
|
|||
|
|
$ yay -S gotop
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Using [yaourt][8]:
|
|||
|
|
```
|
|||
|
|
$ yaourt -S gotop

|
|
Press **< TAB>** to toggle process grouping. To kill the selected process or process group, type **dd**. To select a process, just click on it. To scroll down/up, use the mouse scroll button. To zoom in and zoom out CPU and memory graphs, use **h** and **l**. To display the help menu at anytime, just press **?**.
