16 years later, I had the same question.  My particular mminfo query returned multiple lines of output.  However, each each line of output was preceded by a line with the column headers, so if my query yielded 6 results, the output would have consisted of 6 result lines, and 6 lines of just the column headers  

I'm posting here in case anyone else needs to strip the column headers out of a mminfo query that yields multiple lines of output, another solution is:

pipe the output of the query to "sed 1d"

Example: <your-mminfo-query> | sed 1d
