如何从powershell获取主机名？

Question

How do I get the hostname for dur from powershell?

PS /home/thufir/powershell> 
PS /home/thufir/powershell> ./hostname.ps1                                                                              
google.com
localhost
PS /home/thufir/powershell> 
PS /home/thufir/powershell> cat ./hostname.ps1                                                                          
$hosts = ("google.com", "localhost")

foreach($i in $hosts) {
  $fqdn = [System.Net.Dns]::GetHostEntry($i).HostName
  write-host $fqdn
}
PS /home/thufir/powershell> 
PS /home/thufir/powershell> hostname                                                                                    
dur
PS /home/thufir/powershell> 

The FQDN for the system is actually dur.bounceme.net , which would be the preferred output.

Thanks to bluuf for setting me on the right track :

PS /home/thufir/powershell> 
PS /home/thufir/powershell> [System.Net.Dns]::GetHostByName((hostname)).HostName                                        
dur.bounceme.net
PS /home/thufir/powershell> 
PS /home/thufir/powershell> hostname
