我一直在尝试找出一种方法来递归删除xattr某些文件的所有内容，但是，以前的方法似乎都不再起作用了；可能还有一个新引入的错误？

$ xattr -rc .
option -r not recognized

$ xattr -c .
option -c not recognized

..现在是大结局！

$ find . -exec xattr -l {} \;
com.apple.FinderInfo:
Traceback (most recent call last):
  File "/usr/local/bin/xattr", line 11, in <module>
    sys.exit(main())
  File "/Library/Python/2.7/site-packages/xattr/tool.py", line 200, in main
    print(_dump(attr_value))
  File "/Library/Python/2.7/site-packages/xattr/tool.py", line 77, in _dump
    printable = s.translate(_FILTER)
TypeError: character mapping must return integer, None or unicode

哦，看它xattr在泥土中发现了一个……知道如何，什么或谁xattr如此严重地破坏了该工具会很有趣。我只需要递归地删除扩展属性，真的！

您似乎xattr在 /usr/local/bin/xattr 中安装了一个非标准命令（macOS 附带的标准命令是 /usr/bin/xattr）。这些是 Python 错误，所以也许是这个？无论如何，它不使用与标准语法相同的语法，因此安装它会引起混乱；我建议将其删除或重命名为不同的名称；否则可能会破坏任何尝试使用xattr.

这也发生在我身上。我相信是由于我的$PATH

/usr/local/bin:/usr/bin

我user local bin在我之前system usr/bin。

感谢这些帖子，我发现了问题所在。

xattr 安装在两个位置。

显示目标是内置、函数、别名还是外部可执行文件。（来源） /

type -a xattr
# xattr is /usr/local/bin/xattr
# xattr is /usr/bin/xattr

他们肯定是不同的。

/usr/local/bin/xattr -h
usage: xattr [-slz] file [file ...]
       xattr -p [-slz] attr_name file [file ...]
       xattr -w [-sz] attr_name attr_value file [file ...]
       xattr -d [-s] attr_name file [file ...]

The first form lists the names of all xattrs on the given file(s).
The second form (-p) prints the value of the xattr attr_name.
The third form (-w) sets the value of the xattr attr_name to attr_value.
The fourth form (-d) deletes the xattr attr_name.

options:
  -h: print this help
  -s: act on symbolic links themselves rather than their targets
  -l: print long format (attr_name: attr_value)
  -z: compress or decompress (if compressed) attribute value in zip format

VS。

/usr/bin/xattr -h
usage: xattr [-l] [-r] [-s] [-v] [-x] file [file ...]
       xattr -p [-l] [-r] [-s] [-v] [-x] attr_name file [file ...]
       xattr -w [-r] [-s] [-x] attr_name attr_value file [file ...]
       xattr -d [-r] [-s] attr_name file [file ...]
       xattr -c [-r] [-s] file [file ...]

The first form lists the names of all xattrs on the given file(s).
The second form (-p) prints the value of the xattr attr_name.
The third form (-w) sets the value of the xattr attr_name to the string attr_value.
The fourth form (-d) deletes the xattr attr_name.
The fifth form (-c) deletes (clears) all xattrs.

options:
  -h: print this help
  -l: print long format (attr_name: attr_value and hex output has offsets and
      ascii representation)
  -r: act recursively
  -s: act on the symbolic link itself rather than what the link points to
  -v: also print filename (automatic with -r and with multiple files)
  -x: attr_value is represented as a hex string for input and output

因此，如果您出于某种原因确实想保留两者，那么您可以像这样显式调用它们：

/usr/bin/xattr -lr ~

/usr/local/bin/xattr -l ~
