递归xattr失败可怕

我一直试图找出一种方法来递归删除某些文件的所有xattr,但是,previous methods似乎都不再有效;可能还有一个新引入的bug?

$ xattr -rc .
option -r not recognized

$ xattr -c .
option -c not recognized

..现在是最后的结局!

$ 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,看起来它在泥土中找到了xattr ...知道如何,是什么或谁破坏了xattr工具会很有趣。我只需要递归删除扩展属性,真的!

您似乎在/ usr / local / bin / xattr中安装了非标准xattr命令(macOS附带的标准命令是/ usr / bin / xattr)。那些是Python错误,所以也许它是this one?无论如何,它没有使用与标准语法相同的语法,因此安装它会导致混淆;我建议将其删除或重命名为不同的东西;否则,它可能会破坏尝试使用xattr的任何脚本(您的或系统)。

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。

由于这些帖子,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。(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想要保留两者,则可以像这样明确地调用它们:

/usr/bin/xattr -lr ~

/usr/local/bin/xattr -l ~
