Welcome to the spellbook. Its goal is to provide reference to reference and useful code snippets for *nix server administration tasks. Most entries will provide several lines of code which allow to accomplish desired task at once. If accomplishing task can be achieved without editing any configurations files, only from command line, it will be described in such a way.

In here I don't have goal to make documentation per se, because there is a saying which states that “Those who don't understand UNIX documentation are condemned to repeat it. Poorly.” So there won't be any in-depth explanations. Just a sequence of commands which allow to accomplish a task. If there is any misunderstanding of what the particular command does, referencing to the man page for it is implied.
