Calling SQL Server database from Unix

With oracle currently there开发者_开发问答 is a way to call a database through a command prompt using sqlplus. I'm wanting to know if there is a way to call a SQL Server server the same way so that I can have a shell script do it for me. Is there a way?

fisql

A complete replacement of the isql utility programs distributed by Sybase and Microsoft. > Like them, fisql uses the command "go" on a line by itself as a separator between batches.
