Ok,

this just as an exercise.

Follow this stream from top down, and try to find a better solution!

I am curious!

Jan, 100 pts for showing up the Eunuchs weenies...

Well,

I must admit,
I HAVE been boasting a little, and I only CAN, because of... Guy Peleg.

In my solution, I used some of the qualifiers that Guy only recently introduced, and presented here in Nashua with his usual enthousiasm. You WILL need the last 732 or 82 DCL kit.

Never mind older versions (AFAIK).

install Perl on Vms, and use the Perl option ?

gawk :== disk:gawk
(in tcpip$examples.snmp, if memory serves me), and use awk ?

Dcl is not a good tool here IMHO

[Bojan Nemec]

Jan,

You give the response in the link.
But how to do this on an older VMS version without the new qualifiers?
Need more than one command ;)

$ DIR /COL=1/NOHEAD/NOTRAIL/OUT=ALL.TMP
$ SEA /WIN=0/OUT=FND.TMP
$ DIFF FND.TMP ALL.TMP/SEP=REVISION/MATCH=1

Some more work it will be needed to clean the result from the header and footer.

PS,

Maybe a hint for Guy. Why not add two qualifiers to DIFFERENCES: /HEAD and /STATISTICS and respective /NOHEAD and /NOSTATISTICS which will give you only the different records (of course with /NONUMBER).

hey,

the whole thing is about HOW to get these results IN UNIX, remember?

I normally only read those threads in an attempt to get a feeling for the Unix way of looking at things, and solving issues.

And ONLY because so many different people came to different constructs, which turned out no solutions, I came to do the excersize about how I would solve it.

AFAIK perl is there on *X as well, and more widely spread as on VMS, so I think any pearl solution would not even need the detour via VMS.

And as a practical solution the infrastructure will indeed not very often be there..

One approach to doing this on Yeew-Nix! would be to install a simh VAX and run VMS on it, then do it on VMS.

:-D

(Do I need to explain Yeew-Nix! ??? :-)

[Garry Fruth]

Jan, I am speaking from memory, and did not try this on a VMS machine yet. But I suspect your solution is incorrect:
$ SEARCH [...]*.*
"

File ABC.TXT contains:
a
b
c

SEARCH abc.txt a,c/MATCH=NOR/LIMIT=1/SILENT
will indicate ABC.TXT as a solution, even
though it contains "A". The question as I
interpreted it stated that they wanted files that did not contain ANY of the search strings. I think Bojan's solution (for which you awarded only 1 point) hits the mark; although I have not tested it.

[Jan van den Ende]

Anyone able to verify Garry´s statement?
If he is right, that would pull the whole basement from under this stream :-(

I defer giving points till after verification.

Proost.
