How to send sms from file

Hi All,

########################
SMS Sending and Receiving
Use smsd if you need both to send and to receive SMS. You can use it
with a file or a database backend.

If you only need to send, you can also use gnokii --sendsms, which
reads message body from stdin.

I am unable to find an option to let sendsms read from file.

If i using echo command, there is always a "" in the text.
