为什么我的批处理脚本给出了下面的错误“‘’是不识别的”？

Question

我创建这个批处理脚本是为了提取以前连接到我设备的任何Wi的密码。这个脚本要求用户输入SSID，然后使用netsh wlan show profile=%Wi-Fi name% key=clear提取密码，但是在执行时，我多次遇到这个错误：' ' is not recognized as an internal or external command, operable program or batch file.。

我尝试用实际的代码(即cmnd语句中的netsh wlan.... )替换变量FOR \f，但是没有明显的输出。

对于做错了什么有什么建议吗？

我的守则：

@echo Welcome to this Password Extractor tool.
set /p WiFi_Name=Enter the SSID.
set cmnd=netsh wlan show profile name=%WiFi_Name% key=clear
for /f "tokens=1-2,17" %%i in ('%cmnd%') do ^ 
if "%%i %%j"=="Key Content" set PASS=%%k
echo%PASS%
Pause

“命令提示符”窗口显示以下错误：

C:\Program Files\PowerToys>set /p WiFi_Name=Enter the SSID.
Enter the SSID.Skti

C:\Program Files\PowerToys>set cmnd=netsh wlan show profile name=Skti key=clear

Answer 1

我建议你用一些更结实的东西：

For /F "Tokens=3,*" %%G In ('%SystemRoot%\System32\netsh.exe WLAN Show Profiles Name^="%WiFi_Name%" Key^="Clear" 2^>NUL ^| %SystemRoot%\System32\findstr.exe /RC:"^  *Key Content  *: *[^ ][^ ]*.*$"') Do Set "PASS=%%H"

…如果您想要分割长行以提高可读性，那么：

For /F "Tokens=3,*" %%G In ('%SystemRoot%\System32\netsh.exe WLAN Show Profiles
 Name^="%WiFi_Name%" Key^="Clear" 2^>NUL ^| %SystemRoot%\System32\findstr.exe
 /RC:"^  *Key Content  *: *[^ ][^ ]*.*$"') Do Set "PASS=%%H"

请注意，netsh.exe输出是以配置的系统语言返回的，因此如果您打算分发此输出，请注意任何密码都不会总是前面有区分英文大小写的字符串Key Content。

它可以解决你的问题。

@ECHO OFF
echo Welcome to this Password Extractor tool.
set /p WiFi_Name=Enter the SSID: 
netsh wlan show profile name=%WiFi_Name% key=clear>"%tmp%\wifi.log"
findstr /n "Key Content" "%tmp%\wifi.log">"%tmp%\wifi1.log"
del /q /f "%tmp%\wifi.log"
set /p pass=<%tmp%\wifi1.log
for /f "tokens=3 delims=:" %%a in ("%pass%") do (
  SET PASS=%%a
  )
SET PASS=%PASS%B
del /q /f "%tmp%\wifi1.log"
set PASS=%PASS:~1,-1%
ECHO PASSWORD: %PASS%
pause

它在临时文件夹中创建一些必需的文件，并在操作完成后移除。
