Recommendations for powershell profile

April 30, 2021 by Munkhtuvshin Baatar

As i showed in my post about creation of powershell profile you can add into profile your own frequently used functions.

I recommend to name them with permanent prefix. For example i create all my functions as moguy-cdp, moguy-esxi and so on.

In this case you don’t need to remember the name of your function to run, just start typing as moguy… and autocompletion will show you all your functions.

for example:

function moguy-vms

{

Get-VMHost | Get-VM | Select-Object Name, PowerState, NumCpu, MemoryMB, VMhost, @{N="Datastore";E={Get-Datastore -vm $_}}, UsedSpaceGB, ProvisionedSpaceGB, @{Name='ToolsVersion';Expression={$_.Guest.ToolsVersion}}, @{Name=’VMHostVersion’;Expression={$_.VMHost.Version}},Version, @{N="IP Address";E={@($_.guest.IPAddress[0])}},@{Name=’Cluster’;Expression={$_.VMHost.Parent}}, @{N="PortGroup";E={Get-VirtualPortGroup -VM $_}}, @{N="owner1";E={$_.customfields.item("owner1")}} | Export-Csv
