Bulk load on several files

Hello,

I have a directory with 200,000+ ttl files that I want to
load into a TDB database. The command help only specifies the sintaxis
for one file load.
I tried with the following command:

cat ../listaExtraidos.txt | tdbloader2 --loc /home/guidoz/workspace/rdfMaven/database

where listaExtraidos.txt is a space-separated list of ttl files obtained by the ls command.
It hits me this exception:

12:35:17 -- TDB Bulk Loader Start
12:35:17 Data phase
File does not exist: -

Is there any way to do this, or I will need to join the files?

Guido.
