Powershell Read-host input from CSV - powershell

Question

Im trying to get this script to work by instead of me manually inputing sysnames that I can put the servers into csv and script it and give an output of results
It just sits at the prompt waiting for manual input
$csvpath = E:\Tsm.csv
$SvcName = '*tsm*scheduler*'
$dataset = import-csv -path $csvpath
$row = ($dataset | where{$_.hostname -eq $SysName})
$SysName = Read-Host -prompt "Enter the target computer name: "
$Tsm = Get-Service -ComputerName $SysName | Where {$_.name -Like $SvcName}
Write-Host "Service :" $Tsm.DisplayName
Write-Host "Status :" $Tsm.Status
Write-host "Start Type :" $Tsm.StartType
If ($Tsm.StartType -ne 'Automatic')
{
Write-Host "Setting service startup type to Automatic."
Set-Service -InputObject $Tsm -StartupType Automatic
}
If ($Tsm.Status -ne 'Running')
{
Write-Host "Starting the service."
Start-Service -InputObject $Tsm
}
$Tsm2 = Get-Service -ComputerName $SysName | Where {$_.name -Like $SvcName}
Write-Host "Service :" $Tsm2.DisplayName
Write-Host "Status :" $Tsm2.Status
Write-host "Start Type :" $Tsm2.StartType
Export-Csv C:\TestOutput.csv$csvpath = E:\Tsm.csv

Answer 1

There are many ways to get what you want. Basically you shouldn't be using Read-Host, or only use it when you want the prompt and manual waiting.
A couple of points:
# this line uses the $SysName variable, which is asked for in the next line.
# so it will not work correctly.
$row = ($dataset | where{$_.hostname -eq $SysName})
# if you do not want the waiting and pause on screen, remove this line.
# That's the standard way Read-Host works.
$SysName = Read-Host -prompt "Enter the target computer name: "
One possible solution:
param(
[switch]$manual
)
if($manual){
$SysName = Read-Host -prompt "Enter the target computer name: "
}else{
$SysName = "value or variable"
}
With this solution you can call your script using .\script.ps1 for auto-solution or .\script.ps1 -manual for the Read-Host.
