LINUX - apt-get utility

Some examples of uses for the apt-get utility:

• Install a Package: Installation of packages using the apt-get tool is quite simple.
  

  sudo apt-get install <service name>

• Remove a Package: Removal of a package or packages is also a straightforward and simple process. To remove the package installed, type the following:
  

  sudo apt-get remove <service name>

• Update the Package Index: The APT package index is essentially a database of available packages from the repositories defined in the /etc/apt/sources.list file. To update the local package index with the latest changes made in repositories, type the following: 
  
  sudo apt-get update
  
  

• Upgrade Packages: Over time, updated versions of packages currently installed on your computer may become available from the package repositories (for example security updates). To upgrade your system, first update your package index as outlined above, and then type:

  sudo apt-get upgrade
