Is this homework?

2i\
This is the new second line

The only complicated bit is how to get the quoting right. For an 'sh' type
shell, just put the command in single quotes.

sed -e '2i\
new second line' filename

For a 'csh' you might be lucky with

sed -e '2i\\
new second line' filename

sed '1s/$/\nnew second line/' myfile.txt

That probably only works with GNU sed. Most versions of sed
don't treat \n in the replacement string as special.
