有条件(例如/h或其他条件)以管理员身份打开程序 [英] Open a program as administrator with conditions (e.g. /h or something)

问题描述

我想使用 Start-Process 批量但有条件地使用PowerShell运行程序.

I want to run a program with PowerShell using Start-Process in a batch but with conditions.

我对其进行了测试，并使用 Start-Process 命令运行了 cmd/c .

I tested it and I ran cmd /c using the Start-Process command.

命令:

powershell -Command "Start-Process `cmd /c` -Verb runas"

那没有用.

所以我在PowerShell上对其进行了测试.尝试了相同的命令，并返回此错误:

So I tested it on PowerShell. Tried the same command and it returned this error:

Start-Process : A positional parameter cannot be found that accepts argument
'runas'.
At line:1 char:14
+ Start-Process <<<<  'cmd /c' -Verb runas
    + CategoryInfo          : InvalidArgument: (:) [Start-Process], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.StartProcessCommand

如何使用 powershell 命令在主PowerShell上批量处理此问题?

How can I make this work on batch using powershell command and on the main PowerShell?

推荐答案

反引号是PowerShell的转义字符.在声明中

The backtick is PowerShell's escape character. In a statement

Start-Process `cmd /c` -Verb runas

反引号转义 cmd 的 c 和/c 后的空格.前者没有问题，因为它只是使 c 成为文字 c (无论如何).但是，转义/c 和 -Verb 之间的空格有效地将整个序列/c -Verb 变成单个字符串.基本上，与您运行以下语句相同:

the backticks escape the c of cmd and the space following the /c. The former isn't problematic, because it just makes the c a literal c (which it is anyway). However, escaping the space between /c and -Verb effectively turns the whole sequence /c -Verb into a single string. Basically it's the same as if you'd run this statement:

Start-Process cmd "/c -Verb" runas

自 Start-Process 仅接受2个位置参数( -FilePath 和 -ArgumentList )，其他所有参数都必须通过命名参数传递.因此，关于没有位置参数接受参数 runas 的错误.

Since Start-Process accepts only 2 positional parameters (-FilePath and -ArgumentList) everything else must be passed via named parameters. Hence the error about no positional parameter accepting the argument runas.

像这样运行命令:

Start-Process cmd /c, dir, "$env:windir\temp" -Verb runas

或

Start-Process -FilePath 'cmd.exe' -ArgumentList '/c', 'dir', "$env:windir\temp" -Verb runas

或类似(来自CMD):

or like this (from CMD):

powershell.exe -Command "Start-Process cmd /c, dir, \"$env:windir\temp\" -Verb runas"

，它将按您期望的那样工作.

and it will work as you'd expect.

修改
由于显然一开始还不够清楚: -ArgumentList 参数的参数是逗号分隔的列表(数组).

Edit
Since apparently it wasn't clear enough initially: the argument for the -ArgumentList parameter is a comma-separated list (an array).

Start-Process cmd /c, dir, "$env:windir\temp" -Verb runas
#                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
#                       this right here
