Welcome to this Linux reference and tutorial website. Please surf the menus above to dig into the subject you want more information and examples. Be aware though that all the documentation in this website applies to RHEL / CentOS / Scientific Linux version 7 but it might not apply to previous versions or Linux distributions. Bear with me as this website is a continuous work-in-progress: more sections will be added and the current ones will be expanded overtime. For the most immediate to-do's, check coming soon. If you do not know where you can find the term (file or command) you are looking for, then to speed up your search go to Index of contents. Finally, if you have some worthy comment (erratas, suggestions, feedback, etc), feel free to contact me in about the author.
