执行存储在 powershell object 中的 cmdlet 列表

Question

I have list of cmdlets stored in a variable $commands and this is the output of it:

PS C:\Windows\system32> $commands

Get-AzCloudService

Get-AzCloudService_Get

Get-AzCloudService_GetViaIdentity

Get-AzCloudService_List

Get-AzCloudService_List1

How can I execute the commands in $commands one by one.

I have tried to execute this:

$commands | ForEach-Object{$_}

and this:

$commands | ForEach-Object{Invoke-Command -ScriptBlock {$_}}

But both the above lines just displays the cmdlets and doesn't execute them. I have searched everywhere to get it but could not find it.

You almost got it. You are just missing out the call operator & .

$commands | ForEach-Object { & $_ }

To call all commands with the same arguments, add them as usual:

$commands | ForEach-Object { & $_ -arg1name arg1value -arg2name arg2value }

You might want to have a list of commands and accompanying arguments. For this you could use splatting .

$commands = @(
     @{ command = 'foo'; args = @{ arg1name = arg1value; arg2name = arg2value } }
     @{ command = 'bar'; args = @{ arg1name = arg1value; arg2name = arg2value } }
)

$commands | ForEach-Object { 
    $theArgs = $_.args
    & $_.command @theArgs
}

Note that I had to assign the arguments to a variable first, because splatting does not work with member access. It requires a single variable name after the @ .
