Post your distro, how long you've been using Linux, and perhaps even a screenshot.


Distro: Gentoo Linux
Since: About 2002? Cut my teeth on Mandrake Linux 7.0 and mid kernel 2.4!

I'm gonna move over to Linux one day.

GTS. My company is having me start Linux classes. I will be taking Red Hat 6.0 classes. Is there anything i need to pay real close attention too. I am coming from a iSeries background. So this is new to me will be taking a Fund. and ADM I and ADM II class.

Good for you. RHCE (along with CCNA) are the two most valuable certifications on the market. They are also (not coincidentally) the hardest to BS your way through, as both include practicals where you have to fix real world hardware where you don't know how it is broken.

If it covers SELinux, watch this video from the SouthEast LinuxFest by one of Red Hat's guys who holds every cert they offer: http://www.youtube.com/watch?v=e_dzkYlXggM

I would encourage you familiarize yourself with yum and Red Hat's (bizarre and unique) locations for major config files. Don't expect to move from a RHEL box to ANY other Linux box (except MAYBE Fedora) and find the config files in the same place. I don't know what Red Hat does it ... but ... meh ... they do. I'm assuming you have a basic understanding of UNIX itself coming from IBM-land, and understand that everything in UNIX is a file, etc, etc.

Thanks I will watch this video. Yes I have been on UNIX systems before. I kind of look at it like the MS/DOS file system with the directories and files. Am I close.

Way off.

MS-DOS is direct hardware access. There are no abstraction layers.

There are multiple abstraction layers in Linux and hardware access is managed and there is no stupid "drive" filesystem hierarchy and *everything* is a file. Even hardware.

I can drop down to a command line and go:

$ mplayer /dev/cdrom

and bam it plays.


Or for my analog TV tuner: cat /dev/video0 > testfile.mpg

And bam it starts dumping whatever channel it is tuned to as an MPEG file.

etc.

Assembly language is still useful, if you feel like doing everything with MOV statements...

Assembly language? Good grief. Horrible flashbacks. I thought Fortran sucked until I started my assembly class.

I'm tinkering with Linux at home. Nothing special, just the standard Ubuntu setup, but so far it's playing nicely with some very old hardware.

I started out with 370 assembler, way back in the day...
