What is the command-line completion (also know as tab completion)?
When you type a command you can press the Tab key, and the terminal will complete that command. It simplifies the use of the command line a lot. In this video you will learn how to use the tab completion and how to enable it.

Also, watch how to enable colors in terminal    • My Linux terminal color scheme  

If tab completion doesn't work for sudo, edit the ~/.bashrc file by addin this line to it:

complete -cf sudo

Or install the bash-completion package.

In Arch Linux:
sudo pacman -S bash-completion

In Ubuntu, Debian and Debian-based distros:
sudo apt install bash-completion

In Debian and Debian-based distro, bash-completion sometimes doesn’t work. You need to check your .bashrc file.
It should have this content there

enable programmable completion features (you don't need to enable
this, if it's already enabled in /etc/bash.bashrc and /etc/profile
sources /etc/bash.bashrc).
if ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi

If it doesn’t have it, add it at the end of the file.

To reinstall:
sudo apt install bash-completion --reinstall
