Using Powershell's Invoke-Command to call a batch file with arguments
提问by Jay Spang
I want to use Powershell in order to call a batch file on remote machines. This batch file has arguments. Here's what I have so far:
我想使用 Powershell 来调用远程机器上的批处理文件。这个批处理文件有参数。这是我到目前为止所拥有的：
$script = "\fileshare\script.cmd"
$server = $args[0]
$args [string]::join(',',$args[1 .. ($args.count-1)])
Invoke-Command -computername $server {$script + ' ' + $args}
After a bit of searching, I found that the Invoke-Command function runs its scriptblock in a whole new process, so you can't put variables in it (they won't get expanded). That's what the -ArgumentList tag is for. So I tried this instead...
经过一番搜索，我发现 Invoke-Command 函数在一个全新的进程中运行其脚本块，因此您不能在其中放置变量（它们不会被扩展）。这就是 -ArgumentList 标签的用途。所以我尝试了这个......
Invoke-Command -computername $server {\fileshare\script.cmd} -ArgumentList "FirstArgument"
That didn't work either... my batch script tells me it's not being passed any arguments. I can't find anything that explicitly says so, but it looks like the -ArgumentList parameter only works on Powershell scripts (it won't feed them to a batch script).
这也不起作用......我的批处理脚本告诉我它没有被传递任何参数。我找不到任何明确说明的内容，但看起来 -ArgumentList 参数仅适用于 Powershell 脚本（它不会将它们提供给批处理脚本）。
Any ideas how I can use Invoke-Command to call a batch file with arguments?

When you pass the argument list to the scriptblock, try to "receive them" using a PARAM directive. Like this:
当您将参数列表传递给脚本块时，尝试使用 PARAM 指令“接收它们”。像这样：
Invoke-Command -computername $server {PARAM($myArg) \fileshare\script.cmd $myArg} -ArgumentList "FirstArgument"
or you can just use the $args automatic variable:
或者你可以只使用 $args 自动变量：
Invoke-Command -computername $server {\fileshare\script.cmd $args} -ArgumentList "FirstArgument"

The arguments will be passed as arguments to the scriptblock and not directly to your cmd. You have to do:
这些参数将作为参数传递给脚本块，而不是直接传递给您的 cmd。你必须要做：
Invoke-Command {param($script,$arg1) &$script $arg1 } -computername $server -ArgumentList $script,"FirstArgument"
or
或者
Invoke-Command {&$args[0] $args[1] } -computername $server -ArgumentList $script,"FirstArgument"
PS: I don't know what you are doing with $args [string]::join(',',$args[1 .. ($args.count-1)]), it is a syntax error
PS：我不知道你在做什么$args [string]::join(',',$args[1 .. ($args.count-1)])，这是一个语法错误
