Bill,

I use the following script to scour by a number of files, rather than
by day:


<<<<<<<<<<<<<<<<<<<< scour_bynumber.csh >>>>>>>>>>>>>>>>>>>>>>>>>>
#!/bin/csh -f

if($#argv < 2) then
   echo 'Usage: scour_bynumber.csh directory pattern [number]'
   exit
endif


if($#argv == 3) then
   set KEEP=$3
else
   set KEEP=1
endif

cd $1

set FILES=`ls -r *${2}*`

if($#FILES > $KEEP) then
echo SCOUR $2
   @ COUNT = $KEEP + 1
   while ($COUNT <= $#FILES)
      echo "   scour $FILES[${COUNT}]"
      rm -f $FILES[${COUNT}]
      @ COUNT = $COUNT + 1
   end
endif

**********************************************************************

I use the above script for scouring things like RUC data, where I 
only want to keep the last 1 or 2 runs, instead of 8 per day (leads
to 15 files in a directory at 1 time if using scour).

I invoke the above script like:
scour_bynumber.csh ~ldm/data/gempak/hds ruc2 2

The result of the above is to scour all files in the 
~ldm/data/gempak/hds data directory that have "ruc2" in their name
down to 2 files (the last complete file plus the one currently
getting data).
