Does scp create the target folder if it does not exist
提问by Benoit Paquette
I am wondering if scp will create the target folder if it does not exist on the remote server. For example, would this work?
我想知道如果远程服务器上不存在 scp 是否会创建目标文件夹。例如，这行得通吗？
scp -r /data/install/somefolder [email protected]:/data/install/somefolder
Here the folder /data/install/somefolderdoesn't exist on ftp server, so would this command create it?
这里的文件夹/data/install/somefolder在 ftp 服务器上不存在，所以这个命令会创建它吗？
N.B. I have read about rsync but am not really sure how it works or how to use it yet.
注意我已经阅读了 rsync 但我不确定它是如何工作的或如何使用它。

Short answer: no.
简短的回答：没有。
...but rsync does, which is why I have aliased scpto rsync -Pravdtze sshon my box. Yes, that's a lot of switches, which in combination produces my preferred rsync behavior. As rsync does provide a very extensive set of switches and options, I suggest you do some research on it to see what fits your needs best. Man-page is a good place to start, but there are a lot of info easily available. Here's a decent list of examples.
...但确实rsync的，这就是我为什么别名scp来rsync -Pravdtze ssh对我的盒子。是的，这是很多开关，它们结合起来产生了我喜欢的 rsync 行为。由于 rsync 确实提供了一组非常广泛的开关和选项，我建议您对其进行一些研究，看看哪些最适合您的需求。手册页是一个很好的起点，但有很多信息很容易获得。这是一个不错的示例列表。
Edit:Actually, in that particular case you posted, the folder will be created, as that's the folder you're copying. However, if you're trying to copy it to user@remotehost:somenonexistentfolder/somefolder, then it will fail.
编辑：实际上，在您发布的特定情况下，将创建文件夹，因为这是您要复制的文件夹。但是，如果您尝试将其复制到user@remotehost:somenonexistentfolder/somefolder，则会失败。

To achieve the task with ssh and scp (instead of rsync):
要使用 ssh 和 scp（而不是 rsync）完成任务：
Solution
解决方案
Lets break into 2 steps :
让我们分成两个步骤：
1. Create directory if missing:
1.如果没有创建目录：
ssh [email protected] "mkdir -p /data/install/somefolder"
2. Copy to it:
2.复制到它：
scp -r /data/install/somefolder [email protected]:/data/install/somefolder
Put them together
把它们放在一起
server="[email protected]"
destiny="/data/install/somefolder"
src="/data/install/somefolder"
ssh "$server" "mkdir -p $destiny" && scp -r "$src" "$server:$destiny"
