dbt2-shell script problem

Hi guys,

I get the dbt2 project from the git tree. And i'm trying to make it work
with postgres. The problem is in one of the dbt2 shell scripts. Since I dont
understand of Shell Script Programing, here is my problem: (I will post the
script on the end)

1 - I executed:
dbt2-pgsql-load-db -d /tmp/fodao
2 - I got the error:

dbt2-pgsql-load-db -d /tmp/fodao
[: 77: x: unexpected operator
[: 77: no: unexpected operator
Loading customer table...
COPY customer FROM '/tmp/fodao/.data' WITH NULL AS '';
ERROR: could not open file "/tmp/fodao/.data" for reading: No such file or
directory

3 - I think the correct place should be '/tmp/fodao/customer.data' instead
of "/tmp/fodao/.data"

Can anyone help me with this Bash Script ??

Mant thanks in advace,
Jonas
