[Tutor] concatenating files

[Bala subramanian]

Hai,

I have file1.dat,file2.dat...file 300.dat  in one directory. I want to
concatenate all the files in a single file  (total.dat) with a string "END"
separating the file contents.
my total.dat should be
file1.dat contents
END
file2.dat contents
END
----
----
file300.dat.

now i have another 400 such *.dat files in another directory whose contents
i hve to append to "total.dat", how can i do this task. i need to do
something like, updating the file total.dat without overwritting it.

Thanks,
Bala
