如何将符号链接移至垃圾箱?

我没有看到 FSPathMoveObjectToTrashSync() 函数有任何不跟踪链接的选项。

这是我尝试过的

创建链接和文件

[ 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

将链接移动到垃圾桶

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

输出是

status: 0

但是文件被删除而不是链接

[ 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 ] $

如何将符号链接移动到垃圾桶?


解决方案..感谢 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);

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);

使用 FSPathMakeRefWithOptions() 生成链接的 FSRef。然后使用FSMoveObjectToTrashSync()将其删除。

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

另一种方法是告诉 NSWorkspace “回收”它,方法是发送 a performFileOperation:source:destination:files:tag:消息NSWorkspaceRecycleOperation 操作一条 recycleURLs:completionHandler: 消息< /a>.

我不知道其中任何一个在符号链接上的效果如何,但如果您不想处理 FSRef ,那么值得一试。

The other way would be to tell the NSWorkspace to “recycle” it, by sending it either a performFileOperation:source:destination:files:tag: message with the NSWorkspaceRecycleOperation operation or a recycleURLs:completionHandler: message.

I don't know how well either one of these would work on symlinks, but it's worth trying if you'd rather not deal with FSRefs.

我的复古未来主义方法

https://github.com/reklis/recycle

//
//  main.swift
//  recycle
//
//  usage: recycle <files or directories to throw out>
//

import Foundation
import AppKit

var args = NSProcessInfo.processInfo().arguments
args.removeAtIndex(0)   // first item in list is the program itself

var w = NSWorkspace.sharedWorkspace()
var fm = NSFileManager.defaultManager()

for arg in args {
    let path = arg.stringByStandardizingPath;

    let file = path.lastPathComponent
    let source = path.stringByDeletingLastPathComponent

    w.performFileOperation(NSWorkspaceRecycleOperation,
        source:source,
        destination: "",
        files: [file],
        tag: nil)
}

my retro-futuristic approach

https://github.com/reklis/recycle

//
//  main.swift
//  recycle
//
//  usage: recycle <files or directories to throw out>
//

import Foundation
import AppKit

var args = NSProcessInfo.processInfo().arguments
args.removeAtIndex(0)   // first item in list is the program itself

var w = NSWorkspace.sharedWorkspace()
var fm = NSFileManager.defaultManager()

for arg in args {
    let path = arg.stringByStandardizingPath;

    let file = path.lastPathComponent
    let source = path.stringByDeletingLastPathComponent

    w.performFileOperation(NSWorkspaceRecycleOperation,
        source:source,
        destination: "",
        files: [file],
        tag: nil)
}
