Hi Deb,

It shouldn't work as it is the incorrect syntax.

re:

> FILE     -close somename
> EXEC     somescript somename

This is also the incorrect syntax.

re:
> and
> ^CONDUIT blah blah
> FILE     -close somename
> ^CONDUIT blah blah
> EXEC     somescript somename

This is almost correct.  The correct syntax would be:

CONDUIT<tab>blah blah
<tab>FILE<tab>-close somename

CONDUIT<tab>blah blah
<tab>EXEC somescript somename

NB:
- CONDUIT should begin the line
- <tab> means an actual tab character

re:
> So how do I get EXEC to run as a child AFTER the entire FILE ingest is
> complete?

The EXEC will not run as a child, but the EXEC action will run after
the FILE<tab>-close action if it is after the FILE action in the
pattern-action file.  The inclusion of the '-close- flag to FILE should
insure that the file is flushed to disk so that the following EXEC action
will be working on a complete file.

Cheers,

Tom
