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.

I wrote a script file that does a bunch of things to all the possible partitions of HDA HDB HDC and HDD.
One thing I do is... I attempt to mount them.
If you try to mount a partition that doesn't exist then it spits out the message (for example) "open /dev/hdd12evice not configured"
My "issues" start here... I don't want a lot of useless messages to be displayed. I don't need to know if it failed or not. It must just return clean.
Is there a way I can tell if a partition exists before I try to mount it?
Then I could only mount those.
And, in the same token, is there a way to tell if a HDD exists?
This will also help a lot.
Hmm that's weird. Maybe it's some Redhat/Mandrake way of doing things. I don't have any of those systems around to check, but the ones I did check now all show the hdxX references in /proc/partitions. The man page of fdisk even says when using -l if there are no devices given then the entries in /proc/partitions are used. So that would explain why fdisk -l wouldn't work for you.
Maybe I should check my Mandrake system when I get home, probably also got those weird entries since I've seen them before.
Yep. That's exactly what I did.... but then, I thought... why the hell do I wanna use egrep and awk, they're soooo big, and i'm stingy with my space at the moment. (It's on a boot disk).
So I wrote a little C app of like 10 lines or something.
Statically compiles to about 10k.
All I do is pass it a command line like "hda2" or "hdc" and it returns true or false, which I use in my script file.
