Change the awk delimiter:

Code:
awk -F"|" .....

It seems that your date field is the 7th, so you need to change $3 with $7 in the script.

BTW, I assume the third record you provided is in wrong format!

The method is always the same, just add another array variable to keep the second date you need to manipulate, eg:

Code:
awk -F"|" '{
   split($6, d1, "-");
   split($7, d2, "-");
   $6=sprintf("%04d-%02d-%02d", d1[3], d1[1], d1[2]);
   $7=sprintf("%04d-%02d-%02d", d2[3], d2[1], d2[2]);
   print;
}' input_file.txt

Oh, sure Smilie

Just add the line:
Code:
OFS="|";

before split commands.
