this question的答案似乎对我不起作用，无法将rsync从本地计算机并行化到AWS实例。
我进行了一次试运行，并获得了一个文件列表，其中包含要传输的每个文件的文件路径，将该文件列表拆分为split目录中的59个较小的文件列表。然后，我用每个文件列表的名称split_list.txt创建了一个新的文本文件。我正在尝试打开此文件列表的文件列表，以管道传输到59个并行rsync运行中：
cat split_list.txt | parallel --will-cite -j 59 rsync --relative --human-readable --ignore-existing --files-from={} -rave "ssh -i key.pem" /Volumes/BRIENNAKH\ 4/xml/ [REMOTE-HOST]:~/arxiv/xml
[我认为通过执行cat split_list.txt，我会将split目录中每个文件列表的路径传递给第二个参数，并且--files-from={}参数将接收每个文件列表。
它不运行，而是返回

rsync is a file transfer program capable of efficient remote update
via a fast differencing algorithm.
Usage: rsync [OPTION]... SRC [SRC]... DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
or rsync [OPTION]... [USER@]HOST:SRC [DEST]
or rsync [OPTION]... [USER@]HOST::SRC [DEST]
or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.

我应该如何格式化我的命令，以便可以执行我打算做的事情？
我可以确定在尝试使用“ --files-from”开关执行非常简单的rsync情况时遇到相同的“错误”。任何使用它的尝试都会导致帮助消息的转储，尽管它不会抱怨说它是无效的选项。网上研究表明，“-relative”选项存在或存在错误，这由“ --files-from”暗示。
我的解决方法是在命令行中将“ --files-from=list-file”替换为“ cat list-file”（使用反引号）。
我正在使用LUbunto 18.04LTS，而rsync版本是rsync.samba.org的版本3.1.2协议版本31。这就是Lubuntu（Ubuntu）包装的内容。
谁知道到底发生了什么？
[更新]好吧，在进一步挖掘之后，我发现--files-from = list.txt必须与源目录结合使用。我天真地认为指定列表将相对于当前目录。它不是。它相对于源目录。
因此，以下应该起作用：% rsync -a -r -v --files-from=/someSrc/list.txt /someSrc [remote:]/someDest
并且在简单情况下也是如此。首先测试一个简单的子集，以测试您的复杂案例。
