(For Easily installing/removing packages on Debian based Linux (like Ubuntu) )
Firstly, add alias for installing and removing packages into your .bash_alias file.
#Add alias to file
#ai is short for 'install'
#au is short for 'uninstall'
echo "alias ai='sudo apt install'" >> ~/.bash_alias
echo "alias au='sudo apt remove'" >> ~/.bash_alias
Then copy the files named 'get' and 'remove' into /etc/bash_completion.d folder. (You can also copy it to /usr/share/bash-completion/completions/ folder.) Chmod these files to [-rw-r--r--] (644) (which is usually the default for most system files)
Assuming that Working Directory of your terminal is the root folder of this cloned repository, the following should word fine -
#Copy Files
sudo cp ai /etc/bash_completion.d/
sudo cp au /etc/bash_completion.d/
#Set Permissions
sudo chmod 644 /etc/bash_completion.d/ai
sudo chmod 644 /etc/bash_completion.d/au
Now, open up a terminal and test this command (just download any package and then try to remove it)
Just use it as an abbrevation of normal apt commands.
ai PACKAGE_NAME #install a package
#just like sudo apt install PACKAGE_NAME
au PACKAGE_NAME #remove a package
