Replace end 2 lines of file

[chomps303]

I have to replace the last line of my .profile file with new line and what was origionaly there.

example:
Here is what I have now:

PATH=$PATH:$HOME/bin:/usr3/:/usr/blast:/usr/wp51/wpbin #set command search path
exec /usr/local/bin/mmm
(EOF):


Here is what I want to end with:

PATH=$PATH:$HOME/bin:/usr3/:/usr/blast:/usr/wp51/wpbin #set command search path
PRINTER=39;export PRINTER <<< This was added
exec /usr/local/bin/mmm
(EOF):


Thanks

Perhaps use sed?

sed '$ iPRINTER=39;export PRINTER' .profile > .profile.new

Exactly what I was looking for!!!!

How does it know to use the next to last line?

Thanks so much

How does it know to use the next to last line?
Because on the last line (address=$) we do an insert before (i\ command).

Hope This Help, PH.
