SQL Server Linux(Ubuntu) Connection Options

In general SQL Server Connection Protocols allows three different connection protocols: > 1. TCP/IP > 2. Named Pipes > 3. Shared Memory in linux by default installation we can connect to the SQL Server using TCP/IP, the question is **is there any options for named pipes or shared memory or UNIX sockets?** Also, it seems there is no option to enable or disable such features in Linux. TCP/IP: sqlcmd –S tcp:ServerName –U sa –P Named Pipes: sqlcmd –S np:\\ServerName\pipe\sql\query –U sa –P Shared Memory: sqlcmd –S lpc:ServerName –U sa –P
