我正在尝试将OS X(10.11)中的目录树同步到Ubuntu 14.04.虽然大多数文件传输得很好,但名称以_(下划线)开头的文件却没有.
这是我使用的命令：
rsync -rtvh --progress ~/Pictures/processed/ ~/mnt/processed/
以及输出的一个例子：
sending incremental file list

我的rsync是从自制软件安装的,版本信息：
rsync version 3.1.2 protocol version 31
Copyright (C) 1996-2015 by Andrew Tridgell,Wayne Davison,and others.
Web site: http://rsync.samba.org/
Capabilities:
64-bit files,64-bit inums,64-bit timestamps,64-bit long ints,socketpairs,hardlinks,symlinks,IPv6,batchfiles,inplace,append,ACLs,xattrs,iconv,symtimes,no prealloc,file-flags
使用sshfs挂载远程位置：
sshfs -o idmap=user username@hostname:/some/path ~/mnt -o auto_cache,reconnect,defer_permissions,noappledouble
使用cp命令复制其中一个跳过的文件成功.我尝试添加–iconv = utf-8-mac,utf-8和–include’_ *’选项,这些选项无效.
我究竟做错了什么？
事实证明罪魁祸首是sshfs标志.我用来摆脱.DS_Store文件的noappled double标志实际上干扰了rsync的工作.

This option makes osxfuse deny all types of access to Apple Double (
._) files and.DS_Storefiles. Any existing files will become apparently non-existent. New files that match the criteria will be disallowed from being created.
正如它所指出的,该选项还涉及._ name前缀,这正是rsync用于其临时文件的原因：
rsync: mkstemp "/Users/user/mnt/processed/._MG_7425.jpg.0cAYb3" Failed: No such file or directory (2)
因此,当mkstemp创建临时文件时,sshfs会干扰并阻止它的创建.
从sshfs安装命令中删除noappledouble选项修复了问题,_ *文件已被转移.
感谢@Halfgaar指出我正确的方向.
