Sorry, I thought that you knew what the '\1, \2, ..., \n' mnemonics meant.

When one surrounds a part of a product ID with parentheses in a pattern-action
file extended regular expression, that piece can be referred to/used in the
action part.  The referencing reads from left to right, so the references
above mean the following for the the piece of the product ID:

gefs.*grib2/ncep/SPEC62MRF/#000/(........)(....)F(...)/(.*)/(.*) (Pa)::

!grib2/ncep/SPEC62MRF/#000/200810241200F000/HGHT/250 Pa PRES! 000004

\1 -> (........) which matches 20081024
\2 -> (....)     which matches 1200
\3 -> (...)      which matches 000
\4 -> (.*)       which matches HGHT
\5 -> (.*)       which matches 250
\6 -> (Pa)       which matches PA

If a product with the ID used in this breakdown was received,
the pattern-action file entry:

CONDUIT gefs.*grib2/ncep/SPEC62MRF/#000/(........)(....)F(...)/(.*)/(.*) (Pa)
    FILE -close /data/conduit/GEFS/\4_\5\6_\1_\2_\3.grib2

would create the file:

/data/conduit/GEFS/HGHT_250Pa_20091024_1200_000.grib2
 
> thanks,

No worries.

Cheers,

Tom
