Hello lkeswar,

If file's format will be always prior-product-*_date.txt , then following may help you in same.

 for i in prior-product-*
 do
     echo ${i##*-}
 done

Let me know if you have any queries on same.

The problem is the usual one, how to handle the file if you catch it during upload.

Can the client move the file after upload? Something like

PUT prior-product-purchaseproductpurchase001_20150608.txt /path/to/somewhereelse/prior-product-purchaseproductpurchase001_20150608.txt

RENAME /path/to/somewhereelse/prior-product-purchaseproductpurchase001_20150608.txt /destination/folder/prior-product-purchaseproductpurchase001_20150608.txt

That way, files will always appear in /destination/folder whole and complete, and you can just run this occasionally:

for FILE in /destination/folder/prior-*
do
        mv "$FILE" "${FILE/prior-product-purchase/}"
done
