[Orgmode] Code with line numbers in HTML export

[Saptarshi Guha]

Hello,
I assume in the BEGIN_SRC region, I cannot export the code with line
numbers, however I
came across this
 .linenr            the line number in a code example

Does this mean, there is some option to generate line numbers in the
exported BEGIN_SRC?

Thanks for your time
