Hm, this turns out not to be a bug, but a feature. ;-) Quoting from findutils' NEWS file: -------- * Major changes in release 4.2.21 ** Functional Changes to find
The GNU extension "find ... -perm +MODE" has been withdrawn because it is incompatible with POSIX in obscure cases like "find ... -perm ++r". Use the new syntax "find ... -perm /MODE" instead. Old usages will still continue to work, so long as they don't conflict with POSIX. -------- I'm not sure what "conflicts with POSIX" if you simply use "-perm +x", though. This will probably break a LOT of scripts out there. It's an upstream change that was not very well though-out, IMHO. Even *BSD's find supports the -perm +... construct, so why not support it? The offending change is probably this one: http://savannah.gnu.org/cgi-bin/viewcvs/findutils/findutils/find/parser.c.diff?r1=1.64&r2=1.65
