Using PowerShell script, Ping a list of host names and output the results to a csv-CodePudding

I have a large list of hostnames I need to ping to see if they are pinging or not. I am new at scripting but I managed to figure this much out but getting error when I run this script, I run the script using "PowerShell.exe script.ps > output.csv".

Error Below:

"pinghost.ps : The term 'pinghost.ps' is not recognized as the name of a cmdlet  function    script file     or operable 
program. Check the spelling of the name  or if a path was included   verify that the path is correct and try again. 
At line:1 char:1            
#NAME?          
  ~~~~~~~~~~~           
      CategoryInfo: ObjectNotFound: (pinghost.ps:String) []  CommandNotFoundException       
      FullyQualifiedErrorId : CommandNotFoundException  :"

Code below:

$names = Get-content ".\hnames.txt"

foreach ($name in $names){
  if (Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue){
    Write-Host "$name,up"
  }
  else{
    Write-Host "$name,down"
  }
}

CodePudding user response：

PowerShell will attempt to resolve unqualified file paths passed as command line arguments relative to its working directory - if you launch PowerShell from the Run prompt or as a scheduled task running as a specific local user account, the working directory will default to the users profile folder.

Either pass a rooted file path:

powershell.exe -File C:\Users\Akshay\path\to\pinghost.ps1

Or a file path that's relative to the expected working directory (using / instead of \ will prevent PowerShell from interpreting the path as a module-qualified command name):

powershell.exe -File path/to/pinghost.ps1

In order to make PowerShell's provider cmdlets correctly resolve the hnames.txt file relative to the location of the script itself, prepend the path with the $PSScriptRoot automatic variable:

$names = Get-content (Join-Path $PSScriptRoot hnames.txt)

foreach ($name in $names){
  if (Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue){
    Write-Host "$name,up"
  }
  else{
    Write-Host "$name,down"
  }
}

Now it will work as long as the script and text file are in the same directory, regardless of where you call it from.
