通过Windows批处理文件Plink处理特定错误 [英] Plink handling specific error through Windows batch file

问题描述

我试图解释如何在Windows批处理脚本中捕获一些错误处理，以获取Plink命令的返回代码，例如来自服务器的访问被拒绝"，这意味着我无权访问因此，这意味着我需要访问它.

I'm trying to decipher how I would go about trying to capture some error handling in my Windows batch script for a return code from my Plink command such as "Access Denied" from a server which means I do not have access to it thus meaning I need to gain access to it.

这是代码:

@echo on

SET userid=root
SET passwd=Welcome1%%

for /f "delims=" %%i in ('type "ipaddress.txt" ') do (
pushd "C:\Program Files (x86)\PuTTY"
echo(========================================
plink.exe -pw %passwd% %userid%@%%i hostname
echo(========================================
popd
)

更新代码:

@echo on

SET "userid=root"
SET "passwd=Welcome1%%"

for /f "delims=" %%i in ('type "ipaddress.txt" ') do (
pushd "C:\Program Files (x86)\PuTTY"

plink.exe -pw %passwd% %userid%@%%i hostname 2> logging.txt

type "logging.txt"

findstr /C:"Access denied" "logging.txt"

if errorlevel 1 (
   echo Connected
) else (
   echo Rejected
)
popd
)

我希望打印出成功登录的访问权限，并且第一个for循环可以很好地实现此目的.我要确保的是捕获拒绝的访问，而不是打印失败的主机IP，但继续处理后，它会通过IP地址列表进行处理.

I'm looking to print out the accesses which logon successfully and the first for loop achieves this nicely. What I want to ensure is capturing the access denied and than printing the host IP which it failed against but after continue it's processing through the list of IP addresses.

基于下面给出的详细信息，我甚至尝试了这样的代码设置，以基于简单的o或1个代码使代码保持简单:

Based on the below details given I even attempted such a code setup to keep it simple based on a simple exit o or 1 code:

@echo on

SET "userid=root"
SET "passwd=Welcome1%%"

for /f "delims=" %%i in ('type "ipaddress.txt" ') do (
pushd "C:\Program Files (x86)\PuTTY"

echo(==================
plink.exe -pw %passwd% %userid%@%%i hostname

if ERRORLELVEL 1 (
   echo %%i - Rejected
   echo(==================
) else (
   echo %%i - Connected
   echo(==================
)
popd
)

推荐答案

Plink返回成功的退出代码0或失败的返回代码1.因此，您不能使用退出代码来检查特定的错误类型.

The Plink returns either exit code 0 for success or 1 for failure. So you cannot use the exit code to check for a specific error type.

不过，您可以使用 findstr命令在Plink的错误输出中搜索特定的错误消息.

Though, you can use findstr command to search for the specific error message in the error output of the Plink.

plink.exe -pw %passwd% %userid%@%%i hostname 2> errors.txt

type errors.txt

findstr /C:"Access denied" errors.txt

if errorlevel 1 (
    echo Success or different error
) else (
    echo Access denied
)
