确定批处理脚本是否已从命令行 (cmd) 启动/执行 - 或 - 暂停还是不暂停？

发布于 2025-01-08 18:54:08 字数 365 浏览 1 评论 0原文

我喜欢在我的 cmd.exe 脚本中使用典型的“usage:”行 - 如果缺少参数，系统会简单提醒用户如何使用该脚本。

问题是我无法安全地预测潜在用户是否会使用 GUI 还是 CLI。如果使用 GUI 的人在资源管理器窗口中双击此脚本，他们将没有机会读取任何内容，除非我暂停窗口。如果他们使用 CLI，暂停 会打扰他们。

所以我正在寻找一种方法来检测它。

@echo off
if _%1_==__ (
    echo usage: %nx0: filename
    rem now pause or not to pause?
)

这方面有好的解决办法吗？

原文

I like to have a typical "usage:" line in my cmd.exe scripts — if a parameter is missing, user is given simple reminder of how the script is to be used.

The problem is that I can't safely predict whether potential user would use GUI or CLI. If somebody using GUI double-clicks this script in Explorer window, they won't have chance to read anything, unless I pause the window. If they use CLI, pause will bother them.

So I'm looking for a way to detect it.

@echo off
if _%1_==__ (
    echo usage: %nx0: filename
    rem now pause or not to pause?
)

Is there a nice solution on this?

您可以检查 %CMDCMDLINE% 变量的值。它包含用于启动 cmd.exe 的命令。

我准备了一个测试 .bat 文件：

@Echo Off
echo %CMDCMDLINE%
pause

当从打开的 cmd.exe 窗口内部运行时，脚本会打印 "C:\Windows\system32\cmd.exe"。
通过双击运行时，它会打印 cmd /c ""C:\Users\mbu\Desktop\test.bat" "

因此，要检查脚本是否通过双击启动，您需要检查 %cmdcmdline% 是否包含脚本的路径。最终的解决方案如下所示：

@echo off

set interactive=1
echo %cmdcmdline% | find /i "%~0" >nul
if not errorlevel 1 set interactive=0

rem now I can use %interactive% anywhere

if _%1_==__ (
    echo usage: %~nx0 filename
    if _%interactive%_==_0_ pause
)

编辑：针对评论中讨论的问题更改实施了修复；编辑示例来演示它们

You can check the value of %CMDCMDLINE% variable. It contains the command that was used to launch cmd.exe.

I prepared a test .bat file:

@Echo Off
echo %CMDCMDLINE%
pause

When run from inside of open cmd.exe window, the script prints "C:\Windows\system32\cmd.exe".
When run by double-clicking, it prints cmd /c ""C:\Users\mbu\Desktop\test.bat" "

So to check if your script was launched by double-clicking you need to check if %cmdcmdline% contains the path to your script. The final solution would look like this:

@echo off

set interactive=1
echo %cmdcmdline% | find /i "%~0" >nul
if not errorlevel 1 set interactive=0

rem now I can use %interactive% anywhere

if _%1_==__ (
    echo usage: %~nx0 filename
    if _%interactive%_==_0_ pause
)

Edit: implemented fixes for issues changes discussed in comments; edited example to demonstrate them

我ぃ本無心為│何有愛 2025-01-15 18:54:08

在这里，我写了一些东西...

Usage.bat

@echo off
if arg%1==arg goto help
goto action

:action
echo do something...
goto end

:help
set help1=This is Help line 1.
set help2=This is Help line 2.
cmd.exe /k "echo %help1% &echo %help2%"
goto end

:end

它并不完美，但它有效！ :D-

Here, I wrote something...

Usage.bat

@echo off
if arg%1==arg goto help
goto action

:action
echo do something...
goto end

:help
set help1=This is Help line 1.
set help2=This is Help line 2.
cmd.exe /k "echo %help1% &echo %help2%"
goto end

:end

It's not perfect, but it works! :D

这仅使用内部命令。如此有效....

启用延迟扩展

if "!cmdcmdline!" neq "!cmdcmdline:%~f0=!" pause >nul

或

if not "!cmdcmdline!" == "!cmdcmdline:%~f0=!" pause >nul

禁用延迟扩展

if "%cmdcmdline%" neq "%cmdcmdline:%~f0=%" pause >nul

或

if not "%cmdcmdline%" == "%cmdcmdline:%~f0=%" pause >nul

This is only using the internal command. so effectively....

EnableDelayedExpansion

if "!cmdcmdline!" neq "!cmdcmdline:%~f0=!" pause >nul

if not "!cmdcmdline!" == "!cmdcmdline:%~f0=!" pause >nul

DisableDelayedExpansion

if "%cmdcmdline%" neq "%cmdcmdline:%~f0=%" pause >nul

if not "%cmdcmdline%" == "%cmdcmdline:%~f0=%" pause >nul

开始批量检查 %cmdcmdline% 中的 %WINDIR%，如下所示：

echo "%cmdcmdline%" | findstr /ic:"%windir%" >nul && (
  echo Interactive run of: %0 is not allowed
  pause
  exit /B 1
)

Start your batch checking for %WINDIR% in %cmdcmdline% like this:

echo "%cmdcmdline%" | findstr /ic:"%windir%" >nul && (
  echo Interactive run of: %0 is not allowed
  pause
  exit /B 1
)

请使用 findstr

echo %cmdcmdline% | findstr /ic:"%~f0" >nul && ( pause >nul )

或

setlocal EnableDelayedExpansion
.
.
echo !cmdcmdline! | findstr /ic:"%~f0" >nul && ( pause >nul )
.
.
endlocal

这始终有效...

Please use findstr

echo %cmdcmdline% | findstr /ic:"%~f0" >nul && ( pause >nul )

setlocal EnableDelayedExpansion
.
.
echo !cmdcmdline! | findstr /ic:"%~f0" >nul && ( pause >nul )
.
.
endlocal

This is always worked...

对于内部命令

setlocal EnableDelayedExpansion
set "cmddiff=!cmdcmdline:~0,1!" & if !cmddiff! neq ^" ( pause >nul )
endlocal

或

setlocal EnableDelayedExpansion
set "cmddiff=!cmdcmdline:~28,1!" & if !cmddiff! neq ^" ( pause >nul )
endlocal

您可以比较不同的东西，但这仅在 EnableDelayedExpansion 中有效。而且我不认为这总是有效，因为 Windows 版本等等......

for internal command

setlocal EnableDelayedExpansion
set "cmddiff=!cmdcmdline:~0,1!" & if !cmddiff! neq ^" ( pause >nul )
endlocal

setlocal EnableDelayedExpansion
set "cmddiff=!cmdcmdline:~28,1!" & if !cmddiff! neq ^" ( pause >nul )
endlocal

You can compare the different thing, but this is only worked within EnableDelayedExpansion. and I don't think that this will be always worked, cause windows version, etc...

类似的做法...

setlocal

set startedFromExplorer=
echo %cmdcmdline% | find /i "cmd.exe /c """"%~0""" >nul
if not errorlevel 1 set startedFromExplorer=1

...

if defined startedFromExplorer pause
goto :EOF

Similar approach...

setlocal

set startedFromExplorer=
echo %cmdcmdline% | find /i "cmd.exe /c """"%~0""" >nul
if not errorlevel 1 set startedFromExplorer=1

...

if defined startedFromExplorer pause
goto :EOF

setlocal EnableDelayedExpansion

if "!cmdcmdline!" neq "!cmdcmdline:%comspec%=!" ( pause>nul )

测试是在Windows 10中完成的。使用％windir％，它有点危险或不明确。所以 %comspec% 是超级安全的。

setlocal EnableDelayedExpansion

if "!cmdcmdline!" neq "!cmdcmdline:%comspec%=!" ( pause>nul )

Test is done in Windows 10. Using %windir%, it is a little dangerous or ambiguous. So %comspec% is super safe.

这仅对带有复制和行的逐行输入有效。粘贴批处理程序。当我检测到我将剪贴板复制到 %temp% 文件夹中的 cmd 文件中并要求用户从那里执行该文件时：

set %cmdfile%=%temp%\somecmdfile.cmd

if "%~0" == %0 goto :batch

powershell -c get-clipboard>%cmdfile%

powershell -c "Set-Clipboard -Value '%cmdfile%'"

cls

@echo Please start %cmdfile% manually by pasting to Run (it's in clipboard)

pause

:batch

This is valid only for a line by line entry with copy & paste of a batch program. When I detect that I copy the clipboard into a cmd file in the %temp% folder and ask the user to execute the file from there:

set %cmdfile%=%temp%\somecmdfile.cmd

if "%~0" == %0 goto :batch

powershell -c get-clipboard>%cmdfile%

powershell -c "Set-Clipboard -Value '%cmdfile%'"

cls

@echo Please start %cmdfile% manually by pasting to Run (it's in clipboard)

pause

:batch
