This book contains short descriptions of the most important Linux commands for managing the file system, for starting and terminating processes, for editing text files, for other administrative tasks, and for bash programming. The book also summarizes the syntax of basic configuration files and contains a keyboard shortcut reference for the emacs, nano, and vi editors, as well as some other interactive commands such as lessor info.
The aim of this book is to provide a compact reference work for using Linux in the terminal. The basic principle of this book is: less is more. The book cannot and is not intended to replace the man and info pages of complex commands! Thus, you will still have to look up or research exotic options yourself.
With this book, however, I’m trying to relieve you of the work of searching through the often dozens of pages of original documentation for options for everyday use. Numerous examples also show the basic use of a command at a glance.
Sometimes, you’re looking for a command for a specific task, but don’t know its name or have just forgotten it. The thematically organized table of contents is intended for these cases.
Depending on which distribution you are using, some commands aren’t available by default and must be installed separately. There are also distribution-specific commands that are only available in certain distributions, such as the package management commands dpkg and apt (Debian, Ubuntu), rpm and dnf or yum (Fedora, Red Hat), and zypper (SUSE). This is pointed out in the respective command description.
Linux doesn’t distinguish between commands (as described in this book) and programs such as Firefox, LibreOffice, or GIMP. Here, “command” refers to programs without a graphical user interface, which are usually executed in a terminal window.
In this book, I also describe some commands that aren’t real programs at all, but only commands of the currently active shell. I assume that you’re using the bash (Bourne Again Shell) or the largely compatible zsh. These shells are used in most Linux distributions for the interactive execution of commands. An example of a shell command is cdto change the current directory.
