Bruce,
I know that Simon said Kornshell, but awk would handle this quite elegantly
by setting the record separator (RS = " ") to a blank line and field
separator to a newline (FS = "\n").
Then you could just parse each field, i.e., "name = fred".
Awk would consider this a basic multiline record.

I know exactly what Simon's talking about, I think.
For example, the info in /etc/passwd is in 'record' format, while
/etc/security/passwd is in "stanza" format. It'd be nice to have a routine
that could parse multi-line entries.
It's easy to parse one like the /etc/passwd file, where the fields are
separated by 'colons' (field1:field2:field3:...), but it's much more of a
pain when your record separator is a line of whitespace, not just a line
ending. Example:
Entry1
name = fred
address = 123 Anywhere Lane
address1 = Bungalow A-2
city = RightHere
county = line
province = rightbigone
country = mine
telephone = +012-34-5-67-89
Entry2
name = irving
address = (none)
city = nowhere
telephone = 0000000000
Entry 3
... and so on and so forth.
It would be very nice to have a utility that could:
1. parse all of the stanzas to obtain all member values
2. "flatten" the file into one line, if necessary
3. retrieve a member value (or all) given an entry name
4. Retrieve all entry name with a given member value
5. ... etc.
If I were twiddling my thumbs, this is what I'd write and the way I'd write
it. However, I actually have work to do, so is there some overpaid jock
somewhere willing to do this? perl would be desired. ;-)

Hello Simon,
I dont understand what you want to do.
Could you give an example?
Regards, Holger

Betreff: Scripting: processing stanzas
Is there any utility analogous to getopt that can be used to process
input
data in stanza format? Has to be useable with a Korn shell script,
as I
don't speak Perl or anything clever like that.
If not, any convenient tricks? I'm writing something from scratch,
so I
have complete control over the data format but stanzas would be
simple to
maintain.
