In any case, my question is what do any of you tech heads/fellow Comp Sci guys suggest? I've heard the names Ubuntu and Kubuntu thrown around, do you guys suggest either? I don't have a ton of time to really learn the intricacies but I'd like to become as familiar as I can in the next week or so. By the way, while I may not have a ton of experience using console/command line interfaces I know enough to get around. I've been reading through a Unix For Dummies book to get the basics as well.   | ||

To get the basics it doesn't really matter which one you choose anyway, as they are all the same on the core. But yeah, if you just want a quick get to know tour, take one of the live CDs like Knoppix or Ubuntu (or any other flavor as a matter of fact) offer them and play around with those. | ||

Installing Ubuntu won't help that much, I think you are better off printing a quick Unix/Linux cheatsheet off the internet. | ||

But really I can't think of anything you should learn in particular if they didn't say... just learning how to navigate the filesystem and manipulate files sounds about as basic as they ask. | ||

http://www.amazon.com/Linux-Nutshell-OReilly-Ellen-Siever/dp/0596009305 know how to move around. (., .., ~, ls, cd, ln (symbolic links)) mv (move files), cp (copy files), learn what NOT to do with rm (remove files). probably know bash. know how to add things to your $PATH. (yeah they ask this - most people fall flat on their face). su -, sudo. (aka god mode) Pick vi, emacs, or pico - learn how to use one (they are text editors) - i advocate these as they are looking for command line knowledge probably. Learn how to use grep, awk, and pipes. Know what chown, chmod do. /sbin/ifconfig for basic networking. ping, tracert - you should know these from windows. ssh, telnet (to connect to other devices) scp, rsync (to move files around b/w devices) svn. (versioning control, its easier to learn than cvs) top (tells you whats chewing up your cpu/mem). ps -ef (tells you what processes are running). free (tells you what your memory is doing). kill -KILL (stops things gone wrong) love logs. know basically whats in them (/var/log/allmessages) know what cron is. yay cron (scheduling) Knowing a scripting language is nice. That should get you a basic understanding of how linux works in comparison to windows. Like stated before - dual boot or live cd ubuntu (or suse, or blah, or blah, or w/e really - those two i find the easiest) and force yourself to use it as a desktop for about a week or two. | ||

It'd help to know a little more about the job you're applying for. As other have mentioned, if it is a coding job they probably just require you to be comfortable writing and compiling code in a Linux environment. It is likely that you'll need to use make and gcc to build your code and vim or emacs to write it. You can probably figure a lot of that stuff out with some google searches. If you're applying for an IT job, you'd be best off working on a virtual machine in my opinion. Command line would also be a good idea, as you usually won't have a gui if you just SSH into the various Linux boxes (that's what we do here). Use a server based Linux distribution like Ubuntu server. CentOS is also a good distro to use since a lot of places use Red Hat Enterprise (CentOS is essentially the free version of RHEL). | ||

you will probably need to edit or write a shell script for some functionality. try to google it since most of the common ones are on the net. vim is essential if you don't have gnome or kde. but if you do, you can use gedit, kate, kwrite or even kdevelope etc... but yeah you really have to elaborate more about the job. i suggest openSUSE 10.3 for newbies tho. | ||

Now, someone post the xkcd link about editor wars  | ||

Some details about the job: - It seems to be more IT related, server and user maintenance stuff. If a user requires more space, allocate more to them. If they have PATH issues, fix it. etc. If I get hired, I'd be replacing this other guy that already walked me through what he does on the day to day basis and that's what it sounds like. Support mainly. There are basically a ton of servers that run jobs for users and I would be working to maintain those and help the users. - Most of the coding is writing scripts to simplify tasks. He said he uses something called Kornshell I believe. The only scripting language I have some experience with is PHP, not sure if that's at all similar but for the few seconds he showed me some of the code for his scripts it looked fairly simple. - While it was recommended that I learn Linux, there will be Unix and AIX stuff too. Not sure if that's the relevant info you wanted, ask away if there is anything else important to know. Thanks so much for the help guys, really appreciate it. Edit: By the way, is this the correct VMWare server thing I want? Edit: Also, I'm looking at the various versions of Ubuntu and I assume I want the Server Edition correct? I'm assuming the non-LTS version as well as it is the newer version. | ||

I'm assuming the non-LTS version as well as it is the newer version. Afaik, AIX is based on Unix, and from your description, you will be MUCH better off reading that Linux in a nutshell book than getting Ubuntu. It sounds like it will mostly be done from x-term or cigwin or w/e they use, but there will probably be no UI. | ||

 Php can be used to write maintenance scripts as well - most popular is perl and python i would think - but ive seen pretty much any language used for scripts. Why these instead of C/C++/java for scripts? Well, basically, fast prototyping and proof of concept. I can get a script out in perl to generate some reports, or fix some user PATHing in way less time than C/C++/java. The languages have built in functionality to them which makes them really good at shreading text files, which is basically what youll be seeing alot of in a *nix environment. I guess on a last note - you'll probably want to look over regular expressions a bit. Being a scripting guy, they help alot | ||

Funny you mention reg expressions since I used them quite a bit in php already. Lucky me. | ||
