Hi monks...
Thanks for all the feedbacks... really kick me going...
i manage to get what i want from the coding provided by you guys but i still need another small help.

Understand that grep /\d{6}\.txt$/ will get 051109 from file1_name_051109.txt
but how do i get the same result "051109" from file1_name_051109123024.txt
This is more like a grep problem

Thanks!
