upgrade - One single command to update everything in Ubuntu?

I know that there are three command to update and then upgrade the whole system, these are:

• sudo apt-get update # Fetches the list of available updates


• sudo apt-get upgrade # Strictly upgrades the current packages


• sudo apt-get dist-upgrade # Installs updates (new ones)

Is there a super-upgrade command that combines all these commands to one?

There are 3 decent choices:

1. You could create a script something like the following:

   
   

   #!/bin/bash
   set -e
   sudo apt-get update
   sudo apt-get upgrade
   sudo apt-get dist-upgrade
   

   
   

   Call it something like update.sh and place it in /usr/local/bin and then make the script executable by running:

   
   

   sudo chmod +x /usr/local/bin/update.sh
   




2. Another method would be to create a bash alias (in ~/.bashrc) or wherever you normally store your aliases:

   
   

   alias update='sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade'
   




3. A final method would be to simply string the 3 commands together on the commandline:

   
   

   sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
   

A few choices...
