Please find below Working Code. It's giving error message "Use of uninitialized value $lines1 in substitution (s///) a"

apart from that it's giving a result like in a file01.txt have now file01.txt, in file02.txt have file02.txt only and so on. Old values are deleted and only filename are comeing file.

where as i needed output like

file01.txt have 11 10,9:10/4947000219 :20140924105028 24

file02.txt have 11 10,9:10/4947000220 :20140924105228 24

file03.txt have 11 10,9:10/4947000221 :20140924105428 24

file04.txt have 11 10,9:10/4947000222 :20140924105628 24
