Hi Monks, Seek your wisdom again. My requirement is as follows. I have the following files 
1_ABC.txt
2_ABC.txt
3_ABC.txt
1_XYZ.txt
2.XYZ.txt
5.XYZ.txt

[download]
I have to append all files starting with 1 into a single file (1_AppendFile.txt) and starting with 2 into a single file (2_AppendFile.txt) and so on. I could loop through all the files check the starting value of the file and open a filehandle correspondingly and then print the data into the file. But when I consider file numbers close to 10000 it really gets very slow. Is there any other alternative that we can use here. Regards, Ravi.
