递归 xattr 严重失败

Question

我一直在尝试找到一种方法来递归删除某些文件的所有 xattr，但是，previous methods 的 none 似乎不再有效；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，看它在垃圾堆中发现了一个 xattr...如果知道如何、是什么或谁将 xattr 工具毁得如此严重，那将会很有趣。我只需要递归地删除扩展属性，真的！

Answer 1

您似乎在 /usr/local/bin/xattr 中安装了一个非标准的 xattr 命令（macOS 附带的标准命令是 /usr/bin/xattr）。这些是 Python 个错误，所以可能是 this one？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淆；我建议将其删除或将其重命名为不同的名称；否则它可能会破坏任何试图使用 xattr.

的脚本（你的或系统的）

Answer 2

这也发生在我身上。我相信是由于我的 $PATH

/usr/local/bin:/usr/bin

我的 user local bin 在我的 system usr/bin 之前。

感谢这些帖子，我解决了问题。

xattr 安装在两个位置。

Show whether the target is a builtin, a function, an alias or an external executable.(Source) /

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

而且它们肯定是不同的。

/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，那么您可以像这样明确地调用它们：

/usr/bin/xattr -lr ~

/usr/local/bin/xattr -l ~
