Important system directories

Recognize the small set of directories you will inspect repeatedly while administering Ubuntu.

8 minute lesson

~~~

/etc contains system-wide configuration. /var contains changing data such as logs, caches, and application state. /usr contains installed programs and shared data.

/home contains regular user homes. /root is the root user home. /tmp stores temporary files. /dev exposes device interfaces.

Do not memorize every directory. Learn the purpose of the major ones and use package documentation to find specific files.
