SED help wanted

[balanga]

Could any SED expert help out with this small problem?

I have a short SED script which works using a file sedscr:

s/^/echo '/
s/$/' >>fubar/

which works fine with
sed -f sedscr temp
I'm trying to execute this as a single command:-
sed -e "s/^/echo '/" -e "s/$/' >>fubar/" temp

but can't get it to work. The first part works, but the second part gives me an error

Illegal variable name.

The '$' is supposed to match the end of the line but seems to be getting misinterpreted.

Can anyone explain what I need to do/

The '$' is supposed to match the end of the line but seems to be getting misinterpreted.

You need to escape it. It's because it's within a double quoted (") string which causes the shell to interpret $ as the start of a variable name (and $/ is obviously an illegal variable name).
