in our find. The following are nops because they aren't relevant to our find: -ignore_readdir_race -noignore_readdir_race -noleaf The following aliaes were created: -gid -> -group [2] -uid -> -user [2] -wholename -> -path -iwholename -> ipath -mount -> -xdev -d -> -depth [1] The following new primaries were created: -lname like -name, but matches symbolic links only) -ilname like -lname but case insensitive -quit exit(0) -samefile returns true for hard links to the specified file -true Always true I changed one primary to match GNU find since I think our use of it violates POLA -false Always false (was an alias for -not!) Also, document the '+' modifier for -execdir, as well as all of the above. This was previously implemented. Document the remaining 7 primaries that are in GNU find, but aren't yet implemented in find(1) [1] This was done in GNU find for compatibility with FreeBSD, yet they mixed up command line args and primary args. [2] -uid/-gid in GNU find ONLY takes a numeric arg, but that arg does the normal range thing that. GNU find -user and -uid also take a numberic arg, but don't do the range processing. find(1) does both for -user and -group, so making -uid and -gid aliases is compatible for all non-error cases used in GNU find. While not perfect emulation, this seems a reasonable thing for us.
