Try something like this,

Code:

echo "Are you Bill ?" | sed 's/.* \(.*\) ?/My name is \1/g'

Does it need to be using sed? I don't think that's straightforward...

You only have one "variable" in sed, which is called the "hold space". You can copy or append the current "pattern space" to the "hold space", or you can exchange the two, but inserting the contents of one in the middle of the other is difficult.

You would do much better with awk or perl or similar.

You are right, Thanks,
there is a .sh file to do replacement.sed
what i can do is to modify the replacement file.
how can i use awk in .sed.
Thanks
