UNIX Refresher

[xux42]

What do you want to do with the OS?

Start stop processes?

Change file attributes?

Create command files?

Write some cmd utilities/full blown applications?

AFAIK:
- Read & analyse code to be rewritten, re-compiled on Windows
- edit test data & run tests to verify programs are executing as expected (documentation of existing systems is poor)
- export code & data

I am trying to get more infor from the client but the hiring manager is on holiday for a week - why does that happen so often?

You've blagged it, haven't you?

I'll sell you a copy of my "Porting Linux Applications to Windows in 9999 easy steps..."

If it's an X-Windows type app it might be better recompiling under Cygwin.

Er, I don't know if I have TBH - my PL/1, COBOL etc. on Z/os, Server 2003/8 & XP/Vista knowledge is good and I'm a very experienced in app. devt. & platform migrations.
Unix is well rusty, Agent knows the truth, I can't force him to tell the Client...

Did I just bite?

Quick update - installed Virtualbox - what a fabulous piece of freeware! Powerful yet straightforward to install & configure.
Started installing CentOS 5.4, but didn't quite get the disk configs right (/home too small for CentOS install & no swap disk) so retrying tonight. Couldn't find a DVD iso so had to burn 6 CDs which was a bit of a pain.

All really interesting stuff and setting it up feels like useful experience - virtualisation concepts etc.

Make sure you turn on the Virtualisation stuff in your BIOS (depending on the hardware) and you should see a bit of a hike in performance.

Looks like the DVD is only available via a torrent.

You can install via .ISO

Don't forget to learn vi, the only true gauge of Unix skills!

You can find the DVD .iso here;

1. CentOS installed & running - get quite a lot out of the box - office apps, browser etc. Far more graphical tools e.g file explorer & perf. monitor than the last time I touched Unix in 2000.
Runs smooth, but I see CPU usage shoots up. Fortunately my trusty Athlon 6000+ x2 takes it all in its stride.
Might up from 2GB RAM to 3 or 4 though.

2. Anyone care to translate the :wq!, shift + ZZ gibberish on this thread?
IMHO that kind of obscurity is rarely a good thing. I've always tried to de-mystify IT to end users & managers where possible - that way they believe me when I say something is going to be difficult & time consuming because I don't "always say that".
But then again I'm "Not worth listening to" apparently.
