How to Disable NetBiOS on MacOS OS X

  That seems like a rather strange way to construct that command. Why not just: sudo printf "[default]\nport445=no_netbios\n" >> /etc/nsmb.conf

    That command would run the redirection in the local shell. You can try it out and notice that it doesn't work, because the local shell does not have write access to that file. Shell redirection works by opening the destination file and then dup2()'ing it to stdout before exec??()'ing the target program (sudo, in this case) -- since that open fails, the target program is never even run -- and the open()'ing certainly isn't done after sudo runs, since your shell isn't even part of the execution environment at that point (its image having been replaced by sudo's). Another way to do it, is to invoke a shell that does the redirection after sudo runs, like so: sudo bash -c '( echo blah; echo blah; echo blah ) >> /etc/nsmb.conf'
