John,

The -stats option to gdalinfo should report stuff like the following:

Band 1 Block=512x16 Type=Byte, ColorInterp=Gray
   Minimum=0.000, Maximum=255.000, Mean=104.135, StdDev=58.308
   Metadata:
     STATISTICS_MINIMUM=0
     STATISTICS_MAXIMUM=255
     STATISTICS_MEAN=104.13526916504
     STATISTICS_STDDEV=58.308455229198

Best regards,
