Passing multiple values to a single PowerShell script parameter

The easiest way is probably to use two parameters: One for hosts (can be an array), and one for vlan.

param([String[]] $Hosts, [String] $VLAN)

Instead of

foreach ($i in $args)

you can use

foreach ($hostName in $Hosts)

If there is only one host, the foreach loop will iterate only once. To pass multiple hosts to the script, pass it as an array:

myScript.ps1 -Hosts host1,host2,host3 -VLAN 2

...or something similar.


One way to do it would be like this:

 param(
       [Parameter(Position=0)][String]$Vlan,
       [Parameter(ValueFromRemainingArguments=$true)][String[]]$Hosts
    ) ...

This would allow multiple hosts to be entered with spaces.
