Check the at least one file exists in the directory

Below code is doing file validation properly but returning error after completion second loop. error "file does not existing". my requirement is to check only once if the file exists then it should delete data from table and enter in to the second do loop and print the file names then exit without any error. if there is no single file exists in the directory then should give error.
abc_234.dat abc _123.dat

Code:
INPUTDIR=/path/with/files
for i in $INPUTDIR/abc*.dat
do
        if  [ -f $i ]; then
                echo "delete data from table..."
do
ls -t abc*.dat | sort > ABC.lst
cat  ABC.lst | while read line
do
export file1=$line
echo "${file1}"
done
        else
                echo "File does not exist, exiting.."
                exitcd=44
        fi
done
return $exitcd

Your words are unclear, and your code sample is unclear.
Problably you mean
Code:
NPUTDIR=/path/with/files
exitcd=44
for i in $INPUTDIR/abc*.dat
do
        if  [ -f $i ]; then
                echo "delete data from table..."
                echo "$i"
                exitcd=0
                break
        fi
done
return $exitcd

The break terminates the loop.

you can also try

Code:
#!/bin/bash
cd <PATH>
a=`(ls -lrt  | grep "total 0")`
if [ $? == "0" ]
then
echo "no file
else
<your condition>
fi

May be there are multiple files with different names like STG_123,abc_345,abc_123,STG_345 I need to look only for abc* if at least one abc file exists enter in to the loop and delete the abc files and exit.
