Passing multiple values to a single PowerShell script parameter

Question

I have a script to which I pass server name(s) in $args.

This way I can do stuff to this (these) server(s) using foreach:

.\\script.ps1          


        

Answer 1

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.
