True :-)

Thanks a lot I can hopefully work my way from here...
I thought about sending file A with pattern throufh a fifo then 

As you said it is probably quick and dirty and probably wrong, but the file I 
need to sort is a text file pretty well organised, so I do not have blank 
lines or anything that could mess around.. 

Mkfifo file_A_fifo
name_file_result = echo $fifo (valid ???)
touch name_file_result
cat file_B | grep -i file_A_fifo >  name_file_result

But again ..... considering my experience in this domain....
Anyway thanks a lot and Merry Xmas to all
