用"cmd"执行命令.通过Git-Bash包含空间? [英] Executing Command with "cmd" That Contains Spaces Through Git-Bash?

问题描述

我正在尝试使用cmd使用git-bash执行命令.我需要传递命令才能执行.问题是我需要将批处理文件的路径传递到命令中，并且它具有空格.我似乎无法以能理解的方式将引号传递给"cmd".

I'm trying to execute a command with git-bash using cmd. I need to pass the command for it to execute. The problem is I need to pass the path of the batch file into the command and it has spaces. I can't seem to be able to pass quotes to "cmd" in a way that it will understand it.

cmd//C"c:\ Program Files(x86)\ another path \ file.bat args&& echo done"

那会给我一个错误:

"C:\ Program"未被识别为内部或外部命令，可操作程序或批处理文件.

如果我尝试使用单引号，则会将文字反斜杠传递给cmd.

If I try using single quotes then it passes a literal backslash to cmd.

cmd//C'"c:\ Program Files(x86)\另一个路径\ file.bat" args&回声完成"

哪个错误会给我同样的错误，但是会显示反斜杠:

Which will give me the error the same error but show the backslashes:

'\"c:\ Program Files(x86)\另一个路径\ file.bat \"'不被识别为内部或外部命令，可操作程序或批处理文件.

推荐答案

对于CMD/C，请参阅"针对Windows的Git中的Bash:使用带有args的CMD.exe/C运行命令时很奇怪"

For CMD /C, see "Bash in Git for Windows: Weirdness when running a command with CMD.exe /C with args"

尝试在双引号内使用Unix风格的路径

Try using a Unix-style path, within double-quotes

$ CMD //C "/c/Program Files (x86)/Opera/New folder/a.bat"

(没有完成&&&&&&&& && amp;&&&&&&&&&&&&&&&&&&&&&&&&&&'<"<<<>)

(no && echo done)

在Windows 10上使用git版本2.11.0.windows.1测试.

Tested with git version 2.11.0.windows.1 on Windows 10.

注意:对于简单的命令，不需要 CMD/C 即可从git bash会话执行bat.在这种情况下，您可以转义空格和括号:

Note: For simple commands, you don't need a CMD /C to execute a bat from a git bash session. In that case, you can escape spaces and parenthesis:

vonc@vonc MINGW64 /c/Users/vonc
$ /c/Program\ Files\ \(x86\)/Test/New\ folder/a.bat

OP在注释中添加:

我希望环境变量仅存在于 cmd 的一个实例上.我不希望它实际上在bash中设置环境变量.
这就是为什么"&& "之所以必要的原因，因为另一个命令将依赖于这些变量.这是我唯一需要依赖它们的命令.
cmd/C"C:/vcvarsall.bat的路径&& echo％LIB％" 应打印由批处理文件设置的env变量.
然后在git-bash中，我希望 echo $ LIB 在执行命令后不显示任何内容.

I want the environment variables to only exist on the one instance of cmd. I don't want it to actually set the environment variables in bash.
Which is why the "&&" is necessary, as the other command would rely on those variables. That's the only command I need to rely on them for.
cmd /C "C:/path to/vcvarsall.bat && echo %LIB%" should print the env variable set by the batch file.
Then in git-bash I want echo $LIB to print nothing after executing the command.

echo％LIB％非常棘手，因为CMD会话将使用来自Git的回显，而不是内置CMD shell命令的 echo .但是在 CMD 中链接多个命令(此处适用于Git bash会话)是通过以下方式完成的::

echo %LIB% is tricky because the CMD session would use the echo from Git, instead of the echo builtin CMD shell command.
But chaining multiple command in a CMD (adapted here for a Git bash session) is done with:

cmd //V //C "C:/path to/vcvarsall.bat&&set myvar"

set myvar 将显示bat脚本为 myvar 设置的值.
然而，回到bash会话中， echo $ {myvar} 不会显示任何内容.

set myvar will display the value set for myvar by the bat script.
And yet, back in the bash session, an echo ${myvar} would not display anything.
