For those who are on SunOS which is non-GNU, the following code will help:

sed '$d' tmp.dat > test.dat

I'm not sure I fully understand your question, however this can help you : 

sed -i '$ s/line number//g' file

This will perform substitution only on last line (because of $), replacing line number by nothing.

man sed, section Addresses can help you understand how to apply sed commands on part of the text.
