Thanks for help, you have understood the problem quite well, I have to sort files with same basename present in different directory and subdirectories according to their mtime such that only latest modified file would come in @filelist. Later I have to work on these files separately to fetch some particular data which is working fine for me.I have done changes as per your code but on terminal these errors are coming. Please resolve this issue as I am working on a shared workspace so I can't install any package in linux.
