使用批处理文件运行Unix shell脚本以从WinSCP下载文件

I am trying to download a file from WinSCP through batch file. I am able to download the file if I enter the file name in the batch file.

我试图通过批处理文件从WinSCP下载文件。如果我在批处理文件中输入文件名,我可以下载该文件。

But I need to enter the file name dynamically (i.e., file name has to be entered at run time).

但我需要动态输入文件名(即必须在运行时输入文件名)。

Here is my code

这是我的代码

cd\Users\Desktop\WinSCP
winscp.com /ini=null /script=C:\Users\Desktop\test.txt
open sftp://username:password@hostname/
$ ssh -o "StrictHostKeyChecking=yes" username@hostname
cd /log
get test.log C:\Users\Desktop\Downloading_logs\

here Test.log is the file name I am providing in the batch file.

这里Test.log是我在批处理文件中提供的文件名。

Please suggest a way to enter the file name dynamically.

请建议一种动态输入文件名的方法。

Thanks in advance.

提前致谢。

#1

Use an argument for the batch file

使用批处理文件的参数

Code (script_with_arg.bat):

@echo off

setlocal enableextensions

if "%~1" equ "" (
    echo "Please provide a file name"
    goto :eof
)

cd\Users\Desktop\WinSCP
winscp.com /ini=null /script=C:\Users\Desktop\test.txt
open sftp://username:password@hostname/
$ ssh -o "StrictHostKeyChecking=yes" username@hostname
cd /log
get "%~1" C:\Users\Desktop\Downloading_logs\

echo "Done"

Notes:

• It's the most straightforward way to do this

这是最简单的方法

• The argument is referred to as "%~1". Check [SS64]: Command Line arguments (Parameters) for more details

该参数被称为“%~1”。检查[SS64]:命令行参数(参数)以获取更多详细信息

• The if clause at the beginning is to verify if the argument was provided, if not simply display an error message and exit

开头的if子句是验证参数是否已提供,如果不是简单地显示错误消息并退出

• When dealing with paths, it's always better to dblquote them, as a SPACE in the path might completely mess things up

在处理路径时,dblquote它们总是更好,因为路径中的SPACE可能会完全弄乱

Other ways:

• Use an environment variable (instead of the argument) set from outside the script

使用从脚本外部设置的环境变量(而不是参数)

• Let the user input the file name (via set /p) from the script, as pointed by @ramu246 's comment (I missed this one :) )

让用户从脚本中输入文件名(通过set / p),如@ ramu246的评论(我错过了这个:) :)

@EDIT0:

• After looking at @MartinPrikryl's comment, and doing some tests, it turns out that your .bat file is total crap (so is mine, since it's based on yours)

在看了@ MartinPrikryl的评论并做了一些测试之后,结果证明你的.bat文件是完全废话(因此它是我的,因为它是基于你的)

• However, the fix is still OK, even if it doesn't work (because I applied it blindly - check the previous bullet)

但是,修复仍然可以,即使它不起作用(因为我盲目地应用它 - 检查前一个项目符号)

I did some changes, and below is a version that really works (of course the sensitive data has been altered).

我做了一些更改,下面是一个真正有效的版本(当然敏感数据已被更改)。

script.bat:

@echo off

if "%~1" equ "" (
    echo "Please provide a file name"
    goto :eof
)

winscp.com /ini=winscp_cfg.ini /script=winscp_script.txt /parameter "%~1"
echo "Done"

winscp_script.txt:

echo Received argument: "%1%"
open sftp://cfati:password@127.0.0.1:22001/
cd /tmp
get "%1%" .\"%1%"
exit

Continue connecting to an unknown server and add its host key to a cache?

The server's host key was not found in the cache. You have no guarantee that the server is the computer you think it is.

The server's Ed25519 key details are:

    Algorithm:  ssh-ed25519 256

If you trust this host, press Yes. To connect without adding host key to the cache, press No. To abandon the connection press Cancel.
In scripting, you should use a -hostkey switch to configure the expected host key.

Notes:

• This time I'm using my own paths

这次我正在使用自己的路径

• The .ini file (winscp_cfg.ini) is required in order to pass the host's fingerprint. It's also possible to pass -hostkey argument for open command ([WinSCP]: open), but I wasn't successful (I didn't try too much either)
  • As you can see in the output, 1^st time it requires user confirmation ((Y)es, (N)o, C(a)ncel....), in order to generate the file, and next times it simply uses it

  正如您在输出中看到的,第一次需要用户确认((Y)es,(N)o,C(a)ncel ....),以便生成文件,下次它只需使用它

  • Same thing happened for you (I assume that you wanted to skip the .ini file name), but due to a mistake: Ux's /dev/null equivalent in Win is nul (single l), so winscp_cfg.ini for your case was a file called null

  同样的事情发生在你身上(我假设你想跳过.ini文件名),但是由于一个错误:Win中的Ux / dev / null等价物是nul(单个l),所以你的案例中的winscp_cfg.ini是一个文件名为null

需要.ini文件(winscp_cfg.ini)才能传递主机的指纹。也可以为open命令传递-hostkey参数([WinSCP]:open),但是我没有成功(我也没有尝试太多)正如你在输出中看到的,第一次它需要用户确认( (Y)es,(N)o,C(a)ncel ....),为了生成文件,下次它只是使用它同样的事情发生在你身上(我假设你想跳过它。 ini文件名),但是由于一个错误:Win中的Ux / dev / null等价是nul(单个l),所以你的case的winscp_cfg.ini是一个名为null的文件
