Introduction
A short and functional maintainance script to update and upgrade the packages of an Ubuntu and Debian operating system.
Usage
Either add it as an alias or copy/paste the string of commangs in the terminal and run.
Remove any commands that are not desired including the subsequent
&&.List of Commands
clearremoves any text occupying the terminal window or tty. Used to declutter the screen in preparation for the updates.updaterefreshes the repositories from where packages are pulled to upgrade the system.dist-upgradeis the command that updates all the packages and installs any required dependencies that allow those updated packages to run as intended.autoremoveremoves packages, including dependencies, that are no longer required by the system.cleandeletes packages left in the system for backups.Fail-Safe Mechanisms
Using
&&is my preferred method for a fail-safe mechanism where if the command being executed before that produces an error, the script stops its progress. The rationale behind this is to avoid further endagering the workstation.-fis used as a secondary fail-safe mechanism should&¬ quit the script because of packages incorrectly installed. It repairs errors and ameliorates package dependencies produced by the `dist-upgrade' command.Further Reading
