Create a shell to get data from SQL Server using FreeTDS

Hi guys

I new in Unix and FreeTDS and need your help.

I install FreeTDS 0.82 to connect to SQL Server using the default install:

./configure -prefix=mypath
make
make install

Then I configure my freetds.conf like this:

# MyServer
[MyServer]
        host = xxx.xxx.xxx.xxx
        port = 1433
        tds version = 8.0

I test the connection with tds and the result is OK

# tsql -S myServer -U user -P password
locale is "C C C C C C"
locale charset is "roman8"

Now I want to create a shell that connect to SQL Server using FreeTDS and 
write result data in a text file

How I write this shell? Which libraries I have to use? 

I need install unixOdbc to use libtdsodbc.so library or I can create the 
shell using only FreeTDS?

Thanks
