Thanks a lot, this is exactly what I was looking for ! I didn't expected
that sed would do the job !

what I want can be done like this :
where nbp == 'x' pieces and file == the file I want to split

nbp=8;
file=myfile.to.split;

for i in $(seq 1 $nbp); do
  echo -n "$i~$nbp" >script.file; 
  echo "p" >>script.file;
  cat $file | sed -nf script.file >$file.piece.$i
done;
