Hi all
I have a fasta fileA.fasta which contains 15 sequences and another fasta fileB.fasta which contains 92 sequences.
I would like to find how many of the 15 sequences are also found amongst the 92.
The format. (for both files is the same) is like this:

   >ENST000006553_1908 
   AGCGGGGCCCTT

   >ENST000002542_1826 
   GGGCCTAAAATT

...and so on
