Malicious Linux Commands - From (This article was originally published in Ubuntu Forums but was removed there. Ubuntuguide feels that knowledge about these risks is more important than any misguided attempts to "protect the public" by hiding their potential dangers or protect the (K)Ubuntu/Linux image. ATTENTION: It is worthwhile to have some basic awareness about malicious commands in Linux. It is also worthwhile to always enable a Kubuntu screensaver or Ubuntu screensaver with a password so that a casual passerby is not able to maliciously execute one of these commands from your keyboard while you are away from your computer. When in doubt as to the safety of a recommended procedure or command, it is best to verify the command's function from several sources, such as from readily available documentation on Linux commands (e.g. manpages). Here are some common examples of dangerous commands that should raise a red flag. Delete all files, delete current directory, or delete visible files in current directory rm -r or

HTG Explains: The Linux Directory Structure Explained If you’re coming from Windows, the Linux file system structure can seem particularly alien. 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
