Ten Points Random

Cat and Mouse

by on Feb.08, 2009 @ 10:46 pm, under Technology

So I was working on trying to get the extra mouse buttons on my Logitech G5 to work under Linux and I realized, after I had laid the issue to rest for the night, that I am really rather much of a nerd. The backscroll on my shell window (or, rather, a command I had earlier typed) contained something to this effect:

jon@JonX:/dev/input$ cat mice

And, after having typed it, I actually expected something useful to happen.  Not only did something happen, but it happened just as i expected it to – with the exception of a couple of my buttons that didn’t send any data.

Anyhow, I thought that was rather random: Telling my computer to hand “mouse” to “cat” actually is a valid thing to do.

(For those that don’t waste their life away in front of a green and black [my preferred colors] terminal screen like I do, “cat” is a program, short for “concatenate”, which allows you to see or write to the contents of file(s) directly with the screen/keyboard.  Also, on Linux, input/output devices have virtual “files” associated with them which, in essence, allow you to read and write directly to/from the device, such as a mouse.  Hence “cat mice” will dump all the input form all the mice on the computer to your screen in the form of all sorts of funny heart shapes and strange glyphs.)

    Huh, I think I might cry. I actually understood that.
