The graphical user interface of *NIX operating systems are managed by an “X server”.
GNOME 3 is the most popular desktop environment on Linux.
The computers in our lab were replaced with Ubuntu 17.10, some running Ubuntu’s GNOME, and others on Budgie (which is more lightweight).
The official release date of Ubuntu 17.10 is October 19, 2017. The beta is unstable. Ubuntu 17.10 features a modified version of GNOME 3. GNOME is not a lightweight desktop environment, and might suffer from performance issues on the hardware we use.
Filesystem Hierarchy Standard
/is the root of the filesystem, which holds all your system files.
/homeis where your user’s directory is located. You have write access to your home folder only. Your home folder is denoted as
~(tilde) by most shells, and it contains your documents, pictures, configurations, and other ordinary files.
/binis a symlink to
/usr/bin, which contains executable binaries.
/bootcontains static files for the bootloader.
/devholds “block devices”. Physical and logical devices can be interacted with through their block devices in
/dev/sdarepresents the first physical drive.
/dev/sda1is the first partition on that drive.
/dev/nullis a pseudo-device that behaves much like
nullin any context of computer science. It discards any data written to it.
/etc/contains configuration files.
/libholds shared libraries.
/procprovides information about running processes and the kernel.
/usris a seconday heirarchy containing mostly read-only data.
