You could use vim if it is to be interactive.  If you want it scriptable 
and you know what line numbers you want deleted then you can do it with 
an ed script.  There is probably a prettier way of doing it then this, 
but this just popped into my head:

echo "deleting lines 5 to 10"
echo "5,10dw" | ed filename.txt

for this you could try something like:

echo "getting last line from 'command-you-want-line-from'"
command-you-want-line-from | tail --lines=1 >> file-to-append-to.txt

Just some ideas, ed and tail both have good man pages too.
