Help me with a simple sed script please!

[Leif Andrew Rump]

I'm creating a shell script that set up the DISPLAY environment variable:

	set remote = `who am i | grep "("`
	if "$remote" != "" then
	  setenv DISPLAY	cphxd3:0.0
	endif

I would like to make this shell script "global" so everybody could use it,
but that means that "cphxd3:0.0" must be replaced with whatever the user
is sitting at. I figured that a sed script could solve my problem but how?

	setenv	DISPLAY	`sed ??? $remote`:0.0
