#Unix Toolbox

This document is a collection of Unix/Linux/BSD commands and tasks which are useful for IT work or for advanced users. This is a practical guide with concise explanations, however the reader is supposed to know what s/he is doing.

##Unix Toolbox revision 14.4

The latest version of this document can be found at http://cb.vu/unixtoolbox.xhtml. Replace .xhtml on the link with .pdf for the PDF version and with .book.pdf for the booklet version. On a duplex printer the booklet will create a small book ready to bind. This XHTML page can be converted into a nice PDF document with a CSS3 compliant application (see the script example). See also the about page.
