I've never seen '1' after the 's' command; what should that do?

It replaces the first match. For instance,

marcus@linux:~> echo -e "foobarbar\nfoobar" | sed -e 's/bar/xxx/2'

Ah, nice - found it in the manual now, thanks!

Still, I don't think this is needed for shebang replacement. Instead,
limiting the address range of the 's' action to line number 1 seems more
useful to me.

Have a nice day,
