Mixing
Passing multiple values to a single PowerShell script parameter
I have a script to which I pass server name(s) in $args.
This way I can do stuff to this (these) server(s) using foreach:
.script.ps1 host1 host2 host3
foreach ($i in $args)
{
Do-Stuff $i
}
I'd like to add a named optional parameter called vlan. I've tried:
Param(
[string]$vlan
)
foreach ($i in $args)
{
Write-Host $i
}
Write-Host $vlan
It works if you pass a -vlan parameter but if you don't then the script auto assigns the last server name to $vlan.
So, how can you pass single or multiple parameters plus an optional named parameter to a PowerShell script?
Ideally, here are valid examples:
.script.ps1 host1
.script.ps1 host1 host2 host3
.script.ps1 host1 host2 -vlan office
powershell parameters

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.

Parameters take input before arguments. What you should do instead is add a parameter that accepts an array, and make it the first position parameter. ex:
param(
[Parameter(Position = 0)]
[string]$Hosts,
[string]$VLAN
)
foreach ($i in $Hosts)
{
Do-Stuff $i
}
Then call it like:
.script.ps1 host1, host2, host3 -VLAN 2
Notice the comma between the values. This collects them in an array

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.
