Welcome!

This is steve-parker.org, the internet home of Steve Parker.

Who are you?

I am an IT Consultant, author of the Bourne / Bash shell programming tutorial at https://www.shellscript.sh/, and of the book Shell Scripting (published in 2011 by Wiley in paper and ebook formats) as well as various other Linux related books (also available in various formats).

I am also Director of SGP IT Consultancy Ltd. Please see SGP IT.com for information about what the company offers, including UNIX and Linux training.

I don't often visit LinkedIn, but you can find me at https://www.linkedin.com/in/sgparker/.

What are your credentials?

You can find my CV here: Steve Parker, Linux, DevOps Consultant.

I am a UNIX/Linux consultant with over 18 years experience working with Enterprise class customers, specialising in Clusters, High-End Servers, Volume Management and Storage. I have a proven track record with customers, suppliers and partners in the IT industry. Please do see my CV for more details.

Particular areas of expertise are clustering (Sun Certified Systems Installer for SunCluster 3.x), storage (Sun Certified Data Management Engineer - VxVM, SDS) and UNIX and Linux - scripting, tuning and configuring. I am also a RedHat Certified Engineer (RHCE) and Sun Certified Systems Administrator for Solaris 10. More recently, I have been working with Agile development teams in a DevOps capability, working with Jenkins, Gerrit, Sonar, and so on.

What can I find on this website?

Vanishingly little of interest; the Bourne / Bash shell programming tutorial used to be here, but has moved to its own home at https://www.shellscript.sh/. The Shell Scripting Tips have also moved to https://www.shellscript.sh/tips/.

There is a Facebook page on Shell Scripting which I manage (see to the left).

You will find Linux Tips, for general Linux administration and survival tips.

You can find my CV here: Steve Parker, Linux, DevOps Consultant.

I have various other articles, but they are not particularly interesting.

There is also a basic Networking Tutorial, introducing IPv4 concepts and fundamentals.

If you want a walkthrough of installing and configuring a LAMP Server, you can find that here. Please be aware that the way the PHP code uses the database is not current best practice, but it is enough to get you up and running.

There are other things, like a Grid Multiplication page, which demonstrates a method for simplifying multiplication tasks (without a calculator). All you need is multiplication up to 9x9 and addition.
