SFTP to send file with bash script
提问by Bing
I'm using key authentication, so password is not an issue. I have a file whose name I know and I simply want to send it to another machine over sftp.
我正在使用密钥身份验证，因此密码不是问题。我有一个文件，我知道它的名字，我只想通过 sftp 将它发送到另一台机器。
I tried searching but couldn't find this (seemingly simple) question anywhere. Perhaps my Google-fu is simply failing me today.
我尝试搜索，但在任何地方都找不到这个（看似简单的）问题。也许我的 Google-fu 今天让我失望了。
In short: I'm on my local machine, want to send a file (test.txt) to a remote machine. Authorized keys are already provided. Basically I want to automate these three steps:
简而言之：我在我的本地机器上，想将文件 (test.txt) 发送到远程机器。已提供授权密钥。基本上我想自动化这三个步骤：
sftp root@remote:/root/dropoff
put test.txt
quit
Is there a simple bash command I can use to automate this? The only option I've seen is using a bash script to perform the put/quit and using the -b option to run it. Is there anything cleaner than that? (I'm not interested in using any other applications/tools.)
是否有一个简单的 bash 命令可以用来自动执行此操作？我见过的唯一选项是使用 bash 脚本来执行放置/退出并使用 -b 选项来运行它。还有比这更干净的吗？（我对使用任何其他应用程序/工具不感兴趣。）
Thanks!
谢谢！

You said that you are not interested in other tools, but scpis a much better choice for unattended file transfers. Here is an scp example:
你说你对其他工具不感兴趣，但scp对于无人值守的文件传输来说是一个更好的选择。这是一个 scp 示例：
scp test.txt root@remote:/root/dropoff

I know this is an old one, but you can also pass arguments to a command with a Here Document
我知道这是一个旧的，但您也可以将参数传递给带有Here Document的命令
You can put the following into a script:
您可以将以下内容放入脚本中：
# The following is called a HERE document
sftp <user>@<remote> << SOMEDELIMITER
put test.txt
... # any commands you need to execute via sftp
quit
SOMEDELIMITER
each additional command will be fed into the command preceeding the <<and SOMEDELIMTERcan be anything you want it to be.
每个附加命令都将输入到 之前的命令中，<<并且SOMEDELIMTER可以是您想要的任何命令。
scp is a great option, however sftp was the only tool I was able to get working when pushing from linux to windows and you're stuck using FreeSSHD in service mode!
scp 是一个很好的选择，但是 sftp 是我从 linux 推送到 windows 时能够开始工作的唯一工具，而您在服务模式下使用 FreeSSHD 时卡住了！

I don't know how sftp was configurable when this question was asked. Anyway, 6 years later, you can put sftp-commands like PUT into a file and then reference this file in your initial sftp-call. The makes the whole process completely non-interactive and easily configurable:
当问到这个问题时，我不知道 sftp 是如何配置的。无论如何，6 年后，您可以将 PUT 等 sftp 命令放入文件中，然后在初始 sftp 调用中引用该文件。这使得整个过程完全非交互式且易于配置：
sftp -i /path/to/ssh-key -b /path/to/sftp-commands.txt root@remote:/root/dropoff
....Where sftp-commands.txt just contains
....其中 sftp-commands.txt 只包含
put test.txt; quit
