Neofetch – Shows Linux System Information with Distribution Logo
|
||
============================================================
|
||
|
||
Neoftech is a cross-platform and easy-to-use [system information command line script][3] that collects your Linux system information and display it on the terminal next to an image, it could be your distributions logo or any ascii art of your choice.
|
||
|
||
Neoftech is very similar to [ScreenFetch][4] or [Linux_Logo][5] utilities, but highly customizable and comes with some extra features as discussed below.
|
||
|
||
Its main features include: it’s fast, prints a full color image – your distributions logo in ASCII alongside your system information, it’s highly customizable in terms of which, where and when information is printed on the terminal and it can take a screenshot of your desktop when closing the script as enabled by a special flag.
|
||
|
||
#### Required Dependencies:
|
||
|
||
1. Bash 3.0+ with ncurses support.
|
||
2. w3m-img (occasionally packaged with w3m) or iTerm2 or Terminology for printing images.
|
||
3. [imagemagick][1] – for thumbnail creation.
|
||
4. [Linux terminal emulator][2] should support \033[14t [3] or xdotool or xwininfo + xprop or xwininfo + xdpyinfo .
|
||
5. On Linux, you need feh, nitrogen or gsettings for wallpaper support.
|
||
|
||
Important: You can read more about optional dependencies from the Neofetch Github repository to check if your [Linux terminal emulator][6] actually supports \033[14t or any extra dependencies for the script to work well on your distro.
|
||
|
||

||
```
|
||

If you want to display the default distribution logo as image, you should install w3m-img or imagemagickon your system as follows:
|
||
|
||
```
|
||
$ sudo apt-get install w3m-img [On Debian/Ubuntu/Mint]
|
||
$ sudo yum install w3m-img [On RHEL/CentOS/Fedora]
|
||
```
|
||
|
||
Then run neofetch again, you will see the default wallpaper of your Linux distributions as the image.
|
||
|
||
```
|
||
$ neofetch

Ubuntu System Information with Logo
|
||
|
||
After running neofetch for the first time, it will create a configuration file with all options and settings: `$HOME/.config/neofetch/config`.
|
||
|
||
This configuration file will enable you through the `printinfo ()` function to alter the system information that you want to print on the terminal. You can type in new lines of information, modify the information lineup, delete certain lines and also tweak the script it using bash code to manage the information to be printed out.
|
||
|
||
You can open the configuration file using your favorite editor as follows:
|
||
|
||
```
|
||
$ vi ~/.config/neofetch/config
|
||
```
|
||
|
||
Below is an excerpt of the configuration file on my system showing the `printinfo ()` function.
