Sometimes, you need to check the uptime of a Windows machine. Here's the Powershell command for that: 1PS C:\> systeminfo|find "System Boot Time" This was tested working under Windows 10 Pro and worth noting that it also works in the old cmd. For other methods, see this article.

Linux systemcmd or init way of rebooting will not work in a Windows Subsystem for Linux or wsl-run Linux. You need to use the Powershell command below: 1wsl --shutdown For other methods, see this article.

Using the example in variable assignment And you want to do something to each variable, you may do the following: 1foreach ($i in $container_ids) { 2$i 3} So for instance, you want to delete all the containers: 1foreach ($i in $container_ids) { 2docker rm $i 3}

From powershell CLI; 1$container_ids=docker ps -qa 2$container_ids In the command above, 1st line does the assignment. 2nd line prints the values. You will then have an output such as the following: 16fc00bc6a 2ba3c76ca3 3a9b4e46eb
