@stephane: Can I simply call this method out of Cocoa?

Ok, i changed it to this:

    args = [NSArray arrayWithObjects:@"-ks",path,nil];
    fromPipe=[NSPipe pipe];
    // fromDu=[[NSFileHandle alloc]init];
    fromDu=[fromPipe fileHandleForWriting];
    NSTask *duTool=[[NSTask alloc]init];


Did you talk of this? And is the memory leak now repaired?

Ok, I put it before the return, hope this helps.

Anyway, I'm getting a *** Uncaught exception:
<NSFileHandleOperationException> *** -[NSConcreteFileHandle
readDataOfLength:]: Bad file descriptor

I'm now using readDataToEndOfFile


@Finley: I'm not using fts because I didn't know about it. :-) Do I
loose something when using du instead of fts?

Thanks for all your fast responses
