how to get parameters from switch or file [duplicate]
This question already has an answer here:
How do I write a PowerShell script that accepts pipeline input?
4 answers
I've seen in the past before I started scripting that a powershell script that requires a hostname parameter. it could either by typed in like Script.PS1 "hostname"
but you could also run the script in the following method:
gc hostnames.txt | script.ps1
and in this way you could list a number of hostnames in your text file.
how is this achieved.
my parameters looks as follows
Param(
[Parameter(Mandatory=$True)]
[ValidateSet("C","K")]
[ValidateNotNullorEmpty()]
[String]$Action,
[Parameter(Mandatory = $True)]
[ValidateNotNullorEmpty()]
[String]$Computers
)

As asked you could use syntax something like
gc hostnames.txt | % { .script.ps1 -Action A -Computers $_ }
and it would call script.ps1 once for each line in hostnames.txt.
The $_ is a placeholder for the current value of the array being iterated by the ... | % ... syntax.

Correct answer. I'd like to add that I personally prefer to make scripts readable by not using 'gc' but Get-Content and not using '%' but ForEach-Object or ForEach. This makes it a lot easier to understand and especially for the ones without a lot of experience.
