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 ran SGP IT Consultancy Ltd from 2010-2019. That was at sgpit.com.

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 DevOps engineer with 25 years professional experience working with UNIX Enterprise class customers, followed by specialising in Linux systems and infrastructure, before focussing on DevOps since 2011.

I have published Shell Scripting: Expert Recipes for Linux, Bash and more with Wiley, as well as self-publishing various books, and the Shell Scripting Tutorial - a highly rated online resource which is also available for purchase. Full list of publications here.

Quasi-random hotspot areas of (now largely obsolete) expertise include 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.

Since 2011 I have been working with Agile development teams in a DevOps capacity, working with Jenkins (CI/CD), Git/Gerrit, Puppet, AWS, Azure, Terraform, and so on, as well as my strong Linux and Shell Scripting skills.

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.

Since around 2019 I have become interested in photography; you can see some of my photos at that link.

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.
