Passing Variables to PowerShell for Custom Scripts

[modem-19]

Hello,

I'm still in the process of creating scripts to onboard new clients that run all of the commands / software installations I want remotely vs the manual means of doing that.

One aspect is that I want to change the name of the PC as well as create a new local admin. I can easily create the powershell script for doing that outside of TRMM. However, where I'm unsure is how to pass the contents of a variable that I want my onboarding script to use that is different for each client.

For example, I'd like to name Client A PC's CLIENTA-PC1 (and incrementing) while Client B's may be PC1-DEPT-CLIENTB. Like wise, if I want to create CLIENT D's local admin account with user "Admin" and password "Passw0rd", how can I enter those variables?

Or would I simply create a different onboarding script for each client that has those variables coded into the script?

I'm just looking for advice on the proper usage of TRMM for this aspect.

Thanks!

all of this could be handled with custom fields and a single script just need to build it to your requirement
for exemple client fields:
hostname organisation=clientname-departement-hostname

agentfield:
Sethostname=PC1

and build a script that will process these informations
it would replace all the "organisation" content with the content of the other feed variable to the script

hostname organisation=clientname-departement-hostname
clientname=asdf
departement=hjkl
sethostname=pc1

would make asdf-hjkl-pc1

ollama puked this and it seems to fit the bill as an exemple add as many var as you wish to use for all clients as you will filter the ones not set by just giving empty stuff

# Read the environment variables
$hostnameorganisation = $env:hostnameorganisation
$clientname = $env:clientname
$departement = $env:departement
$sethostname = $env:sethostname

# Ensure the required hostnameorganisation variable is present
if (-not $hostnameorganisation) {
    Write-Error "The 'hostnameorganisation' environment variable is missing. Exiting."
    exit 1
}

# Replace placeholders in hostnameorganisation if the corresponding variables are present
$newHostname = $hostnameorganisation
if ($clientname) {
    $newHostname = $newHostname -replace "clientname", $clientname
}
if ($departement) {
    $newHostname = $newHostname -replace "departement", $departement
}
if ($sethostname) {
    $newHostname = $newHostname -replace "hostname", $sethostname
}

# Display the result
Write-Host "Generated hostname: $newHostname"

# Rename the computer without restarting
Rename-Computer -NewName $newHostname -Force
Write-Host "Computer has been renamed to $newHostname"

Also made a little exemple script for people on my side on how to pass fields to a script
Some of the people I work with needed it too.
