vi being - the command 'visual' that switches the 'extended' line editor to visual mode
global / regular expression / print looks jolly useful too - its hardly untuitive that this is what 'grep' stands for though....

The sub-culture of brevity in the Unix community is going to slow the learning process down a little methinks.

Saves typing at the command line, but don't these minimalist abbreviations make Unix scripts a bit hard for non-Unix bods to read?

The Unix bod has to imagine himself in a scenario with a knackered system which he has to boot in single user or from cd and the only tools available are the standard Unix ones, with no GUI. The ability to edit files in that mode is core.

I sued to hate vi, but now I embrace it, it works exactly the same on Solaris, AIX, HP-UX and Irix, tho linux seems to add odd bits to it to 'help'....

You really have blagged this - Haven't you?

Have you only had gigs where you had sound commercial experience in all aspects?
This is not a Unix contract. Unix is the source system - just need to know enough to get the apps off & decomm. the unix platform from what I have been told so far.

You wanted tutorials? These vim ones are a bit much for a beginner, but you can get the idea.

don't these minimalist abbreviations make Unix scripts the elite domain of the select few ?

Yes

It's different ways to save and quit in vi.

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.

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.

Couldn't find a DVD iso so had to burn 6 CDs which was a bit of a pain.

You can find the DVD .iso here;

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

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.

You can install via .ISO

[b0redom]

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've blagged it, haven't you?

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?
