This is my geek blog. I am Nick Bair, a Linux user striving for proficiency in all areas of computing–setup and administration, networking, programming, security, and so on.


I use this blog to share things of interest with other Linux users. When I learn something new or do something noteworthy, I often find myself thinking, “I should write that down for next time.” The rationale for this blog is that I can write those things down in a place where they’ll not only be there for me next time, but also for everybody else who might need them.

The subject is broad–Linux & open source–and this is probably not the kind of blog that people want to follow. After all, what are the chances that someone out there is struggling with `psnup` at the exact time that I write about it? And if they’re not struggling with it, what are the chances that they’ll want to read about it at that time? No, I don’t suppose many folks will follow this blog. But my obscure `psnup` use case will be there for them when they need it–via a web search. And it will be there for me the next time I need it.

What does the name mean?

`cat` is short for concatenate, and is the command used in UNIX-based systems to do just that–concatenate files and print the result to standard output. More often than not it is used to view the contents of a single file.

`/dev/blog` is a non-existent device node in the Linux virtual filesystem, a key element of UNIX-based OSes that maps device drivers to files so that other processes can interface with them in a standard way.

So, then, if the device node `/dev/blog` were to actually exist, it would point to a weblog, and one could view its contents by typing `cat /dev/blog` at the command prompt (`$`).
