Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

[Apologies if this belongs in the "Mandriva" distro forum, or elsewhere; I'm new to Mandriva Free 2007 and to post in "Newbies" seemed more appropriate]
I've just installed Mandriva Free 2007 and, generally speaking, I'm very happy with it. Certainly, it seems more reliable and accessible than the other distributions I've tried in the past.
However, something's happening that I've never come across before. When I try to load certain programmes - notably, Azureus - they don't load, and odd files are created on the desktop. These files are titled "core.####" (e.g. "core.5934", "core.5963") and seem to be empty.
What are these files? What am I being told about why these programmes won't load?
Similarly, I've installed FreeCiv and tried to run it. It doesn't load, a "core.####" file is made, and also another file is created too - this one is titled "Unable to create mcop directory". This looks like a kind of error message to me; but why it's been made into a file on my desktop, I can't say.
core files are dumps, they indicate that the process you are trying
to start had a problem. The fact that they're 0 bytes in size has most
likely got to do with the fact that your ulimit settings (man bash ; /ulimit)
are truncating them to that size. If you want to know more about how
and why your programs crash start them using
strace -o some_outputfile your_program
and read the log backwards to see what went wrong.
