how to get the number of sockets

[mcclnx mcc]

how about this one:

 grep physical /proc/cpuinfo | uniq -c
      1 physical id     : 0
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 2
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 4
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 6
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 0
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 2
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 4
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 6
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 0
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 2
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 4
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 6
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 0
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 2
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 4
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 6
      1 address sizes   : 40 bits physical, 48 bits virtual
