Changed a good bit, so I'll post a whole script again, however only the awk part has changed, there are a few changes, so please double check you've got them all if you have problems. I have tested this and it does work.
Code:
#! /usr/bin/ksh
dat=/biddf/ab6498/dev/ctl
cd $dat
files=CARE01_DLY_???_`date '+%Y%m%d'`
awk '{data[NR] = $0; out=FILENAME "new"; file[NR]=out;} END { if ( FNR - 2 != $1) { print "error" ; exit 1 } if ( ARGIND == --ARGC ){ for ( i=2 ; i < NR; i++ ) { print data[i] > file[i] } close(file[i])}}' $files
