Resume in PowerShell 5.1 if exe doesn't finish

Question

I am using a loop (ForEach-Object) in a PowerShell script to connect to different hosts via plink (PuTTY).

plink -ssh $_ -l $user -pw $password -T -batch $command

$_ is the IP address of the host.

The command does an upgrade on the remote host. After the upgrade, the remote host reboots, but the connection doesn't close. So plink/PowerShell waits endlessly. How can I get PowerShell to resume the script?

Answer 1

• You can solve this either on local/PowerShell side by aborting stalled command:
  Powershell Start Process, Wait with Timeout, Kill and Get Exit Code

• Or on remote side (assuming Linux), by running the command on background:
  Run command on server using Plink and keep it running after disconnecting
