I will have to process multiple files with same name [filename.txt] everyday.
My requirement is:
If on a certain day I see that filename.txt exists then the contents of the filename.txt would be added/append
to the former file contents.Each time it sees the file the content would be added.But the header
should not be added
For ex: There exists this file
filename.txt
First Name|Second Name
John|Marshall

Next time I get the same file
filename.txt
First Name|Second Name
Jack|Dowell

I need the next file to become like
filename.txt
First Name|Second Name
John|Marshall
Jack|Dowell
Can you please suggest something? Thanks in advance.
