Methods which process the output from "ls -la" are prone to spurious matches and problems with filenames containing space characters. None of the examples posted so far really work.

Another approach. Find all the files in the directory which were created after midnight. The filenames are available in the centre of the do-done loop if you need to do further processing.

Code:
YYYYMMDD="`date +%Y%m%d`"       # Reversed date yyyymmdd
REFERENCE=/var/tmp/reference.${YYYYMMDD}.$$
touch -t ${YYYYMMDD}0000 ${REFERENCE}
#
ls -1d * 2>/dev/null | while read FILENAME
do
     if [ -f "${FILENAME}" -a "${FILENAME}" -nt "${REFERENCE}" ]
     then
           echo "${FILENAME}"
     fi
done 
#
rm ${REFERENCE}

There is a better method using just "find" but we don't know whether your directory has subdirectories.
