the command "find / -xdev -type f -perm +6000 -perm -1 2> /dev/null" don't work in new linux systems
-perm +mode
Deprecated, old way of searching for files with any of the permission bits in mode set. You
should use -perm /mode instead. Trying to use the `+' syntax with symbolic modes will yield
surprising results. For example, `+u+x' is a valid symbolic mode (equivalent to +u,+x, i.e. 0111)
and will therefore not be evaluated as -perm +mode but instead as the exact mode specifier -perm
mode and so it matches files with exact permissions 0111 instead of files with any execute bit
set. If you found this paragraph confusing, you're not alone - just use -perm /mode. This form
of the -perm test is deprecated because the POSIX specification requires the interpretation of a
leading `+' as being part of a symbolic mode, and so we switched to using `/' instead.
See the complaint on #4039. This doesn't fix that particular
issue (it's somewhat unrelated), but does solve around
a file parsing problem reported by @void-in
