Find read-host value in file list - powershell

Question

I have now moved on to automating IDRAC. My script below will look at a list of servernames and IDRAC IP's. I would like to have a user enter a single Servername "S0000A01PX' or whatever and have it search in a master list for the server IDRAC IP. Right now, the script as it is opens every server's virtual console in the list. I just need it to select only the user entry. How do I have this search the file, find the IP next to the user entered servername, and open only the IDRAC for that servername?
example of what's in the CSV
computername iPiDRAC
S0000A01PX 10.122.2.11
Script
$machinename = ""
$file = Import-Csv 'c:\temp\powershell\Branch Server IDRAC.csv'
$filelength = $file.length
$machine = Read-Host 'What is your Server?'
foreach ($line in $file){
$DRACip = $line.iPiDRAC
$DRACpw=cscript c:\PassGen1.vbs $machinename
$DRACpw=$DRACpw[3]
$DRACip
$machinename
$DRACPW
$openIDRAC="http://"+$DRACip+"/console"
$openIDRAC
start $openIDRAC
write-host "----------"
}

Answer 1

If you are just looking to have a general match and return launch all DRACs that match a simple change can get you there. Where-Object{$_.computername -match $machine}
$machinename = ""
$file = Import-Csv 'c:\temp\powershell\Branch Server IDRAC.csv'
$machinename = Read-Host 'What is your Server?'
$file | Where-Object{$_.computername -match $machinename} |ForEach-Object{
$DRACip = $_.iPiDRAC
$DRACpw=cscript c:\PassGen1.vbs $machinename
$DRACpw=$DRACpw[3]
$DRACip
$machinename
$DRACPW
$openIDRAC="http://"+$DRACip+"/console"
$openIDRAC
start $openIDRAC
write-host "----------"
}
You are mixing output and write-host which could get you into trouble so I would remove some of that extra fluff which I will assume is just there for testing. I don't see where you are using $DRACpw or $machinename unless that is somehow what you need to see in order to sign into the DRAC

Answer 2

I think you want a bit of Where-Object.
For this CSV file:
computername,iPiDRAC
S0000A01PX,10.122.2.11
Import the file as you have been:
$file = Import-Csv 'c:\temp\powershell\Branch Server IDRAC.csv'
Ask your question:
$machine = Read-Host 'What is your Server?'
Look for the server name in your $file array, which will output an object representing that line in the CSV, then get its iPiDRAC property:
($file | Where-Object {$_.computername -eq $machine}).iPiDRAC
10.122.2.11
