Hello, I think this is too weak. find -perm +symbolic_mode stopped being very useful with findutils 4.2.25 because it conflicted with POSIX. The big change in 4.5 is dropping support for -perm +numeric_mode, which might or might not be invalid syntax in POSIX, but does not conflict with POSIX. It does conflict with chmod's intepretation of +numeric_mode, which afaict from https://savannah.gnu.org/bugs/?38474 seems to have been the real reason for dropping findutils' support. - find -perm +numeric_mode is not supported anymore. This syntax is unspecified/unsupported by POSIX. The functionality continues to be available with -perm /numeric_mode. (#38474) cu Andreas -- `What a good friend you are to him, Dr. Maturin.
