Bash Quick Start Guide
In , my Bash Quick Start Guide was published with Packt Publishing. It’s a crash course in writing and reading Bash and POSIX-fearing shell script in general. The aim of the book is to demystify shell and make it pleasant and expressive to write. I answered an author questionnaire for it.

I maintain a blog called Arabesque, with posts mostly about Unix command line tools. Its byline is
Systems, Tools, and Terminal Science. There are reader translations and e-book compilations of many of the articles around the web. Posts have featured in magazines such as BSD Magazine and Hacker Monthly.
Some popular articles:
I’ve contributed articles for the Vim enthusiasts’ website Vimways:
I write a lot of Nagios monitoring plugins. I have published a few of them as user tejr on Nagios Exchange. I also write a fair bit of Vim script for the text editor Vim, mostly just for fun; I publish plugins, filetype plugins, and colour schemes as tejr on vim.org.

I have most experience on Debian GNU/Linux and its ilk, but can work on pretty much any Unix-like operating system. I’m also fond of OpenBSD.
