shell script question

[Jim Harkins]

I have a list of files in which I want to change the word 'foo' to the filename.
What I tried to do was

foreach i (list of files)
	sed 's/foo/$i/' < $i > tmp
	mv tmp $i
end

But what this does is replace 'foo' with '$i', not the filename.  Can anybody
help?  I'm running 4.3 BSD UN*X.  Thanks.
