Graphical vi-vim Cheat Sheet and Tutorial Learning vi or vim is not easy. But it doesn't have to be that difficult, either. It is, in any case, faster, more powerful, and more productive than editing with any other editor, so you would do very well in investing the time and effort to learn it.

By the way, I recently published the definitive article explaining why vi/vim editing is so much better than regular editing.

Openbox This article is about the Openbox window manager in Debian. It covers the installation and configuration of Openbox and provides some information on how to make use of it. Introduction To understand what Openbox actually is, it's important to know the difference between a window manager and a desktop environment. A window manager is the program which draws on your screen the "boxes" in which other programs are run. On the other hand, a desktop environment minds the entire desktop. Openbox is a window manager, not a desktop environment. Openbox can be used alone, without a desktop environment, or it can be used to replace the window manager in a complete desktop environment. Installation The easiest way to install Openbox on a Debian system is using Apt. # apt install openbox Normally, a right-click desktop menu will automatically be generated for you on installation. If, however, your desktop menu is not being auto-generated with DebianMenu, you will have to install the menu package: Files #!

The C:\ drive and drive letters are gone, replaced by a / and cryptic-sounding directories, most of which have three letter names. The Filesystem Hierarchy Standard (FHS) defines the structure of file systems on Linux and other UNIX-like operating systems. However, Linux file systems also contain some directories that aren’t yet defined by the standard. / – The Root Directory Everything on your Linux system is located under the / directory, known as the root directory. /bin – Essential User Binaries The /bin directory contains the essential user binaries (programs) that must be present when the system is mounted in single-user mode. /boot – Static Boot Files The /boot directory contains the files needed to boot the system – for example, the GRUB boot loader’s files and your Linux kernels are stored here. /cdrom – Historical Mount Point for CD-ROMs /dev – Device Files /etc – Configuration Files
