Hold Space

23

Heading translation in `sed`

This has some problems

It leaves the last line of input trapped in the hold space

So:

        $ { p;x; }

Address $ means "the last line of input"

After stashing it in the hold space, we print (p) the line that was there

(The next-to-last line)

Then we extract the last line again (x) and it is automatically printed
