---------------------------------------------------------------------- (0006093) stephane (reporter) - 2022-12-08 16:32 https://austingroupbugs.net/view.php?id=243#c6093 ---------------------------------------------------------------------- One of the issues with find -print0 | xargs -0 cmd and that can make it less safe than find -exec cmd {} + is that if find is killed for some reason, or more generally if xargs' input is truncated, you may end up passing the wrong path to cmd as current xargs implementation that support -0 don't mandate the records be delimited. For instance, a: LC_ALL=C find /var/tmp -name '*.tmp' -type d -print0 | xargs -r0 rm -rf Could end up running rm -rf /var if find gets killed (like because it exceeded some resource limit) just after it has output of block that happened to end on the /var or /var/. I don't know if we can do anything about that as it's likely mandating the 0 delimiter could break some existing applications. (that -r should also be added IMO).
