I submitted prepend to moreutils and Joey was kind enough to point out this could be done with `sponge’.  sponge reads standard input and when done, writes it to a file:

Probably the most general purpose tool in moreutils so far is sponge(1), which lets you do things like this:

% sed "s/root/toor/" /etc/passwd | grep -v joey | sponge /etc/passwd

Two days ago Joey released version 0.29 of moreutils including a patch by yours truly (with much help from Joey).

sponge: Handle large data sizes by using a temp file rather than by  consuming arbitrary amounts of memory. Patch by Brock Noland. version 0.29 changelog

Also, on a non-command line note, I found a video on Joey’s site which I thought was pretty cool, Joey Learns to Fly.
