I need to write a script that takes in variables and makes a share on a remote system.
This works:
Invoke-Command -ComputerName server -ScriptBlock {$a = [WMICLASS]"Win32_Share"; $a.Create("C:\test","test",0)}
But this doesn't:
$sharepath = "C:\test"
$sharename = "test"
Invoke-Command -ComputerName server -ScriptBlock {$a = [WMICLASS]"Win32_Share"; $a.Create($sharepath,$sharename,0)}
I need a way to pass those values somehow.
The remote session can't read your local variables, so you need to send them with your command. There's a few options here. In PowerShell 2.0 you could:
1.Pass them along with -ArgumentList and use $args[$i]
$sharepath = "C:\test"
$sharename = "test"
Invoke-Command -ComputerName server -ScriptBlock {
$a = [WMICLASS]"Win32_Share"; $a.Create($args[0], $args[1], 0)
} -ArgumentList $sharepath, $sharename
2.Pass them along with -ArgumentList and use param() in your scriptblock to define the arguments
$sharepath = "C:\test"
$sharename = "test"
Invoke-Command -ComputerName server -ScriptBlock {
param($sharepath, $sharename)
$a = [WMICLASS]"Win32_Share"; $a.Create($sharepath, $sharename, 0)
} -ArgumentList $sharepath, $sharename
In PowerShell 3.0, the $using:-variable scope was introduced to make it easier:
$sharepath = "C:\test"
$sharename = "test"
Invoke-Command -ComputerName server -ScriptBlock {
$a = [WMICLASS]"Win32_Share"; $a.Create($using:sharepath, $using:sharename, 0)
}
