It also displays number of dpkg and snap packages installed.
Installation in the Terminal

sudo apt-get update
sudo apt-get install neofetch

You can also use terminal commands to switch graphics card. For example, this command will switch to Intel graphics card.
sudo prime-select intel
To switch to Nvidia card:
sudo prime-select nvidia
To check which card is being used right now, run this command:
prime-select query

If you have any problems with an external monitor:
Open this file in your favorite editor (vim, nano, gedit, etc.).
sudo nano /lib/modprobe.d/nvidia-kms.conf
And comment out the the nvidia-drm modeset option.

Change swappiness value, cause default is too high for modern systems.
sudo gedit /etc/sysctl.conf
Add line in the bottom of that text file:
vm.swappiness=10
Press save and then reboot pc.
Also if you're having SSD, then u need to edit one file for it's longer lifespan:
sudo gedit /etc/fstab
And find a line where your system/root/home (usually it's on SDA2) partition has been installed, and after line errors=remount-ro add line after adding,noatime. It should look something like this:
ext 4 errors=remount-ro,noatime
But don't edit efi and swap partitions. Save and reboot.

Moved posts of issues to general help to keep the tutorials and guides clean:
OOM conditions may cause freezes, livelocks, drop caches and processes to be killed (via sending SIGKILL) instead of trying to terminate them correctly (via sending SIGTERM or takes other corrective action). Some applications may crash if it's impossible to allocate memory.
Here are the statements of some users:
"How do I prevent Linux from freezing when out of memory? Today I (accidentally) ran some program on my Linux box that quickly used a lot of memory. My system froze, became unresponsive and thus I was unable to kill the offender. How can I prevent this in the future? Can't it at least keep a responsive core or something running?"
"With or without swap it still freezes before the OOM killer gets run automatically. This is really a kernel bug that should be fixed (i.e. run OOM killer earlier, before dropping all disk cache). Unfortunately kernel developers and a lot of other folk fail to see the problem. Common suggestions such as disable/enable swap, buy more RAM, run less processes, set limits etc. do not address the underlying problem that the kernel's low memory handling sucks camel's balls."
"The traditional Linux OOM killer works fine in some cases, but in others it kicks in too late, resulting in the system entering a livelock for an indeterminate period."
To install from PPA:

Unlike the other shells that need a lot of setting-up to work the way you want them to, fish works perfectly right out of the box.
It ships with the most widely used features already included, which are present when you start using it without needing to install any additional plugins or tweak any configuration files unless you want to. Its syntax is simple, clean, and consistent.
Syntax highlighting is a feature that we all wish our CLI could perform. It saves a lot of time and frustration. Well, fish does it, and it does it pretty well.
It shows you whether your command or the directory to be searched exists before you even hit enter. You’ll know whether you’re typing anything wrong before you hit enter. This makes it easier for people to parse commands, and find errors.
It highlights (most) errors in red, such as misspelled commands, misspelled options, reading from non-existing files, mismatched parenthesis and quotes, and many other common errors.
It also features highlighting of matching quotes and parenthesis. Oh, and it’s pretty, colorful.
The fish community maintains Oh My Fish, which is a shell framework inspired by Oh My Zsh. It offers a lot of beautiful prompt themes and awesome plugins, is lightweight, awesome, and easy to use.
It also offers a web-based configuration feature. Just type:
fish_config
You will land on the website with which you can customize the skin of your shell.
This is an interactive feature of this Shell. You begin typing a command and press the up key to see all the times in the Shell history where you used that command before.
To search the history, simply type in the search query, and press the up key. By using the up and down arrow, you can search for older and newer matches. The fish history automatically removes duplicate matches and the matching substring is highlighted.
These features make searching and reusing previous commands much faster.
Fish suggests commands as you type and shows the suggestion on the right of the cursor, in grey. If you mistype a command, it will show in red to indicate that it’s an invalid command.
It also suggests the most frequently used commands and auto-completes while you type, based on your history and valid files available.
Fish can parse CLI tool man pages in various formats. Type in a command and “tab” through all the suggested auto-completions.
sudo apt install fish
Once the installation is completed, you can start using it by switching your current shell to Fish, for that type-
fish
After using some time, if you like this colorful and friendly shell, then you can set it system default instead of bash.
chsh -s /usr/bin/fish
Log out of your system and log in again to apply the changes.
To change Fish properties, we can create a configuration file-
nano ~/.config/fish/config.fish
If you didn’t like Fish and want back your Bash again on the terminal, then run
chsh -s /usr/bin/bash
log out and log in again.
To learn more about this shell command see the official documentation.
source: Command to Install fish shell on Ubuntu 20.04 LTS - Linux Shout
df: shows usage for file system disk space.
du: estimates disk usage for files, directories.
ls -al: displays all the contents of a folder.
stat: shows the status of a file and file system.
Ubuntu also has a GUI-based tool called ‘Disk Usage Analyzer’ for analyzing disk usage. Likewise there is another tool ‘GDU Disk Usage Analyzer’ to view disk usage on many Linux-based distros and macOS.
GDU is written in ‘Go’ language and the official GitHub page frames it as ‘Pretty fast disk usage analyzer’ particularly for SSDs. It also works for HDDs but the performance is not as efficient as in SDD.
