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