Like many administrators, I have numerous scripts written as .BAT batch files that could use an update. Now that Windows Server 2008 R2 has PowerShell 2 installed by default, it is time.
Let's take a few of the staples that we have put in .BAT files, and I'll give you the PowerShell equivalent.
Reboot a remote computer
To perform a 10-second delay on a remote server (Server1), the following is entered in a batch file:
shutdown /r /m \\SERVER1 /f /t 10
In a PowerShell file, the equivalent is:
Start-Sleep 10 Restart-Computer -Force -ComputerName SERVER1
Restart a service
To restart the DNS cache service on a Windows Server, the following would have been entered in a batch file:
sc stop dnscache sc start dnscache
Within PowerShell, the equivalent is:
Map a drive
In a DOS window or a batch file, the following command would be used to map a drive to a network computer:
Net use L: \\server1\c$
With a PowerShell prompt, the equivalent is:
New-PSDrive -name L -psprovider FileSystem -root \\server1\c$Note: A PSDrive is not the same as other drives; this file system space is contained to PowerShell.
While these are the simplest commands, if you replace your day-to-day scripts with PowerShell, you will be equipped with better scripts. These scripts can include richer automation options, yet still be launched interactively in PowerShell.
