The Austin Group has been asked whether future POSIX should include the sponge(1) utility:
https://www.austingroupbugs.net/view.php?id=1927 Before the Austin Group decides whether to sponsor such an addition, I'm trying to get feedback on whether standardizing the utility would be worthwhile, or whether there are lurking caveats (such as difficulties in implementing sponge to do atomic content changes correctly) where we might be better off leaving it non-standard. Right now, many GNU/Linux systems get sponge from moreutils; if POSIX were to mandate sponge, would that be something we try to move into coreutils rather than relying on moreutils? I also note that busybox does not (yet) have a sponge applet, as far as I can tell, but would likely add one if POSIX mandates the utility. -- Eric Blake, Principal Software Engineer Red Hat, Inc.
