结果

tag-icon • tag-icon macos unix filesystems hfs+
结果

我正在尝试确定 Mac OS X 上带有 Mac OS Extended (Journaled) (HFS+) 的常规文件（而不是符号链接等）的所有属性。这是我当前的列表：

Compression State
Unix Permissions
User
Group
extended attributes (xattr)
last access time (stat)
last data modification (stat)
last file status change (stat)
archived flag (chflags)
opaque flag (chflags)
nodump flag (chflags)
sappend flag (chflags)
schg flag (chflags)
uappend flag (chflags)
uchg flag (chflags)
hidden flag (chflags)
ACLs
File Type Code
File Creator Code
Resource Fork
Hard Link Count

有人能想到我可能遗漏的其他属性吗？

准备

使用OS X Mountain Lion：

macbookpro08-centrim:~ gjp22$ ls /Volumes/spare/touched.txt
ls: /Volumes/spare/touched.txt: No such file or directory
macbookpro08-centrim:~ gjp22$ touch /Volumes/spare/touched.txt

结果

谢谢文件Xray：

笔记

添加日期

FndrExtendedDirInfo并且FndrExtendedFileInfo——两者都包括date_added——出现Apple 为 Mac OS X 10.7 开源（xnu-1699.22.73）但不是 10.6.8。

其他领域

对于保留的字段，我不知道现在或将来会有什么用途。

对于 OS X 10.8.2
