Thanks all

I can do it with
wc -l *.dat | awk '{print $1"|"$2}'

result are the same that I want
but I need more
the result after use those command will be

1234|test1.dat
2345|test2.dat
3456|test3.dat
7035|total
and end of file
I want after "7035|total" and then hit the newline like this
1234|test1.dat
2345|test2.dat
3456|test3.dat
7035|total

and end of file
If I see this file with vi
will see like this

1234|test1.dat
2345|test2.dat
3456|test3.dat
7035|total

but I want this
1234|test1.dat
2345|test2.dat
3456|test3.dat
7035|total

How can I do this?
