 sum_<INPUT FILENAME>.YYYYMMDDhhmmss.csv

 
 sum_details_<INPUT FILENAME>.YYYYMMDDhhmmss.csv

 
 I process them in the loop above case statement
 for *.${Today}.*.txt *.${TODAY}*.csv
 do
 firstpreffix=`echo ${file} | cut -d'_' -f 1`
 case ${firstpreffix} in
      sum)
            if [ $file = "sum_INPUT FILE" ];then
                  do something
            else
                  do something
           fi
 esac
 done

 
 if [ $file = sum_*.*.csv ];then

case $file in 
  sum_details_*.*.csv)
    do something ;;
  sum_*.*.csv)
    do something else ;;
sac

 file sum_*.*.csv will get sum_details_*.*.csv. sum_* and sum_detail*...
