That is exactly what i am looking for. Because the file is already sorted.

That is not what you asked for.... ):
- anyway one key per file is far easier than the stuff we mentioned earlier.

Code:
 awk  -F'|'  '{ file=sprintf("%s.txt", $1); print $0 > file }' filename

creates files named 1.txt, 2.txt, and so on. Plus the input file did not really need to be sorted in any way to do the split.
