如何为命令 net user 在列表中返回的每个用户运行批处理文件？

我的目标是制作一个通用代码，循环遍历计算机中的所有用户帐户名称并将输出发送到批处理文件。 “net user”命令输出用户列表，但我想将每个用户名分配给一个参数。所以我应该使用for /f命令去做。这可能看起来很简单，但请记住用户名可能在任何位置包含空格：开头、结尾或中间，此外，还可以找到 2 个连续的空格

提示1：用户名的最大长度为20个字符
提示 2：循环需要遍历错误的用户名，因此需要检查它们是否有效。命令net user "uName" sets %ErrorLevel%如果用户名“uName”（例如）有效，则为 0。

如果没有办法，也许 VBScript 可以使用每个用户帐户名启动批处理文件。

Edit:我终于编写了自己的代码，但是只需要15个帐户就需要大约5秒。

我想要一个更好的解决方案，也许使用另一种编程语言。

setlocal EnableDelayedExpansion
For /f "skip=4 delims=" %%I in ('net user') do (
    Set "Line=%%I"
    If not "!Line:~-1,1!" == "." for %%I in (0,25,50) do (
        Set "Name=!Line:~%%I,20!"
        Call :setName
    )
)

Set Name=
:setName
If not "!Name!" == "" (
    Net user "!Name!" && %~dp0Test.bat "!Name!"
    If not "!Name:~-1,1!" == " " goto:eof
    Set "Name=!Name:~0,-1!"
    Goto setName
)

endlocal

根据我的测试，名称开头或结尾带有空格的用户帐户名是不可能的。用户帐户名称中的非空白字符之间只能有空格。

这是我评论的批处理解决方案，它也不是很快。

@echo off
rem Process output of command 'net user' line by line with skipping
rem the first 4 lines and stopping processing when line with success
rem message is reached which of course depends on language of Windows.
for /F "usebackq skip=4 delims=" %%L in (`%SystemRoot%\System32\net.exe user`) do (
    if "%%L"=="The command was successfully executed." goto :EOF
    call :ProcessAccounts "%%L"
)
goto :EOF

rem Subrountine to process a line with user account names.
:ProcessAccounts
rem Get the line without the double quotes.
set "Line=%~1"

:NextUser
rem Get first 20 characters from line and next remove those 20 characters.
set "Name=%Line:~0,20%"
set "Line=%Line:~20%"

rem Remove all spaces at end of current user account name.
:TrimRight
if "%Name:~-1%"==" " (
    set "Name=%Name:~0,-1%"
    goto TrimRight
)

rem Check if this user account name is valid.
%SystemRoot%\System32\net.exe user "%Name%" 1>nul 2>nul
if not errorlevel 1 (
    echo Valid user account name is: %Name%
    rem Do here what should be done with this user account name.
)

rem Remove leading spaces from remaining line.
:TrimLeft
if "%Line:~0,1%"==" " (
    set "Line=%Line:~1%"
    goto TrimLeft
)

rem Is the shortened line now completely processed?
if not "%Line%"=="" goto NextUser

rem Exit the subroutine ProcessAccounts.
goto :EOF

也许有更好的解决方案来修剪左右空间，请参阅如何删除批处理文件中用户提供的输入的尾随和前导空格？ https://stackoverflow.com/questions/3001999/

该批处理文件执行速度慢的原因是：

%SystemRoot%\System32\net.exe user "%Name%" 1>nul 2>nul
if not errorlevel 1 (
    echo Valid user account name is: %Name%
    rem Do here what should be done with this user account name.
)

通过将此块更改为

echo Valid user account name is: %Name%
rem Do here what should be done with this user account name.

使批处理文件变得非常非常快。

用户帐户名的验证net user "%Name%"使批处理文件如此缓慢。
