如何将符号链接移动到垃圾桶？ [英] How to move a symlink to the trash?

问题描述

我没有看到 FSPathMoveObjectToTrashSync（）没有任何选项用于未关联的链接。

是我尝试过的

创建一个链接和一个文件

  [21:32:41 / tmp] $ touch my_file 
 [21:32:45 / tmp] $ ln -s my_file my_link 
 [21:32:52 / tmp] $ la 
共8 
 drwxrwxrwt 12 root wheel 408 17 Maj 21:32。 
 drwxr-xr-x @ 6 root wheel 204 9 Sep 2009 .. 
 -rw-r  -  r-- 1 neoneye wheel 0 17 Maj 21:32 my_file 
 lrwxr-xr- x 1 neoneye wheel 7 17 Maj 21:32 my_link  - > my_file 
  

将链接移至垃圾箱

  OSStatus status = FSPathMoveObjectToTrashSync（
/ tmp / my_link，
 NULL，
 kFSFileOperationDefaultOptions 
）; 
 NSLog（@status：％i，（int）status）; 
  

输出为

  status：0 
  

但是文件已删除，

  [21:32:55 / tmp] $ la 
共8 
 drwxrwxrwt 11 root wheel 374 17 Maj 21： 33。 
 drwxr-xr-x @ 6 root wheel 204 9 Sep 2009 .. 
 lrwxr-xr-x 1 neoneye wheel 7 17 Maj 21:32 my_link  - > my_file 
 [21:33:05 / tmp] $ 
  

如何移动移动符号链接到垃圾桶？

解决方案...感谢Rob Napier b
$ b

  NSString * path = @/ tmp / my_link; 
 OSStatus status = 0; 
 
 FSRef ref; 
 status = FSPathMakeRefWithOptions（
（const UInt8 *）[path fileSystemRepresentation]，
 kFSPathMakeRefDoNotFollowLeafSymlink，
& ref，
 NULL 
）; 
 NSAssert（（status == 0），@failed to make FSRef）; 
 
 status = FSMoveObjectToTrashSync（
& ref，
 NULL，
 kFSFileOperationDefaultOptions 
）; 
 NSLog（@status：％i，（int）status）; 
   
 
解决方案
使用 FSPathMakeRefWithOptions / code>生成到链接的FSRef。然后使用 FSMoveObjectToTrashSync（）将其删除。
 
I don't see any options for the FSPathMoveObjectToTrashSync() function for not following links.

Here is what I have tried

Create a link and a file
[ 21:32:41 /tmp ] $ touch my_file
[ 21:32:45 /tmp ] $ ln -s my_file my_link
[ 21:32:52 /tmp ] $ la
total 8
drwxrwxrwt   12 root     wheel   408 17 Maj 21:32 .
drwxr-xr-x@   6 root     wheel   204  9 Sep  2009 ..
-rw-r--r--    1 neoneye  wheel     0 17 Maj 21:32 my_file
lrwxr-xr-x    1 neoneye  wheel     7 17 Maj 21:32 my_link -> my_file
Move the link to the trash
OSStatus status = FSPathMoveObjectToTrashSync(
    "/tmp/my_link",
    NULL,
    kFSFileOperationDefaultOptions
);
NSLog(@"status: %i", (int)status);
Output is
status: 0
However the file got removed and not the link
[ 21:32:55 /tmp ] $ la
total 8
drwxrwxrwt   11 root     wheel   374 17 Maj 21:33 .
drwxr-xr-x@   6 root     wheel   204  9 Sep  2009 ..
lrwxr-xr-x    1 neoneye  wheel     7 17 Maj 21:32 my_link -> my_file
[ 21:33:05 /tmp ] $
How can I move move symlinks to the trash?



The Solution.. thanks to Rob Napier
NSString* path = @"/tmp/my_link";
OSStatus status = 0;

FSRef ref;
status = FSPathMakeRefWithOptions(
    (const UInt8 *)[path fileSystemRepresentation], 
    kFSPathMakeRefDoNotFollowLeafSymlink,
    &ref, 
    NULL
);  
NSAssert((status == 0), @"failed to make FSRef");

status = FSMoveObjectToTrashSync(
    &ref,
    NULL,
    kFSFileOperationDefaultOptions
);
NSLog(@"status: %i", (int)status);

解决方案
Use FSPathMakeRefWithOptions() to generate an FSRef to the link. Then use FSMoveObjectToTrashSync() to delete it.
