The next 2 lines need NOT to be deleted.

1, 1, Es_1_1, Study_Es_1_1, 2.10.2014 11:27:18, 2.10.2014 11:27:45, 165188, 0, 0, 4, 0, 715, 0

1, 1, Es_1_1, Deeds_Es_1_1, 2.10.2014 11:27:46, 2.10.2014 11:27:49, 234, 0, 0, 2, 0, 214, 0

1. The script shall delete all entries where the first 4 characters of the third feature matches Es_5 or Es_6
