问题
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:
$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...
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).
Any ideas how I can use Invoke-Command to call a batch file with arguments?
回答1:
When you pass the argument list to the scriptblock, try to "receive them" using a PARAM directive. Like this:
Invoke-Command -computername $server {PARAM($myArg) \\fileshare\script.cmd $myArg} -ArgumentList "FirstArgument"
or you can just use the $args automatic variable:
Invoke-Command -computername $server {\\fileshare\script.cmd $args} -ArgumentList "FirstArgument"
回答2:
The arguments will be passed as arguments to the scriptblock and not directly to your cmd. You have to do:
Invoke-Command {param($script,$arg1) &$script $arg1 } -computername $server -ArgumentList $script,"FirstArgument"
or
Invoke-Command {&$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
