concatenating similar files in a directory
Hi,
I am new in unix.
I have below requirement:
I have two files at the same directory location
File1.txt and File2.txt (just an example, real scenario we might have File2 and File3 OR File6 and File7....)

File1.txt has :
Code:
header1
record1
trailer1

File2.txt has:
Code:
header2
record2
trailer2

I want to keep File2.txt as below and delete the File1.txt.

File2.txt will have:
Code:
header2
record1
record2
trailer2

Can anyone please provide some help here.
