I am not a big fan of using command line utilities in general. But from time to time I do explore and play around with command line tools that make my life easier. Having said that, when working with SQL Server, I do often give out the recommendation of not trying to use the native xp_cmdshell commands with SQL Server. Even the SQL_Server_2012_Security_Best_Practice_Whitepaper talks about xp_cmdshell and recommends to avoid the same if it is possible. These are basic building blocks of security that I highly recommend my customers from time to time.
