Save the output of a powershell command in a variable and use it in batch script?

问题

What I am trying to do is to save the output of a powershell command (run from a batch script) and use it in the batch script.

Can you please advise me what to do?

The power shell comand is:

[System.Net.Dns]::GetHostByName((hostname)).HostName

I want to use the output in the batch script.

P.S.

It will be even better if I can get the full computer name/hostname/fully qualified domain name (FQDN) from cmd and not from powershell. But the full computer name is not the concatenation of the ComputerName and the UserDNSDomain variables.

回答1:

for /f "tokens=*" %%i in ('powershell /command "[System.Net.Dns]::GetHostByName((hostname)).HostName"') do set return=%%i
echo %return%

回答2:

You can do this in batch using nslookup which does the same DNS-search:

for /f "tokens=1*" %%a in ('nslookup hostname ^| findstr /i "name"') do set return=%%b
echo Hello '%return%'
