New What's wrong with JCL?

// DD DSN=ALL.MAKES.PERFECT.SENSE,DISP=SHR
//*
//* ... or something.

Actually you're right, it's about as evil as it is scary. And that's rather a lot in both cases.

New Ironic you should pick...
...the one element of JCL that's most closely preserved in its original form in Unix. Or has nobody else wondered where the dd command comes from? It's a port from the low-level data manipulation tools on MVS.

Ironically, it's also a good argument that there's no rule regarding intuitive interfaces: the dd argument syntax is entirely appropriate for MVS, but doesn't match the Unix environment at all.

What part of "gestalt" don't you understand?
New Wasn't originally written as a joke?
Unix's dd, i mean, not JCL.

New Perhaps both :)
JCL couldn't possibly have been the product of a sane mind. :)

never thought about the dd link though - I just thought it meant Dataset Definition on the MVS side, and no idea what it meant on the unix side. Well there ya go, maybe I just learned something.

New Tape management, IIRC
Most of the core functionality of dd is most useful (and most frequently used) when pulling data from tapes. Given that tape was pretty much Lingua Franca for transferring MF data from the 1970s through the 1990s, and various low-level formatting issues (blocksize, packing factors, buffering, etc., etc.). The syntax was in common enough use, I suppose that it was adopted for Unix when dealing with data originating on Mainframe systems. Not a joke, sorry to say.

Google, as usual, [link|http://www.google.com/search?q=unix+dd+command+history|is useful].

New Yup, I love the unix dd
In a Data Warehousing environment, it proved to be invaluable on a number of occasions.

I'm amused Google spat out an ad for me to search my family history :) Maybe I have a long lost relative caleld Dee-Dee or something.

Interesting stuff to read whilst I'm stuck at work, anyway.

New OT: re 'Lingua Franca' (edit is for a typo)
Now that the defacto language of international business and politics seems more often to be English than French, is it time to change the phrase to 'lingua engla'?

New Re: OT: re 'Lingua Franca'
Consider: a latin phrase for use of French now refers to English....

<sigh>

Try to look unimportant; they may be low on ammo.
