(2017-06-08) WHOAMI, The PowerShell Way

Many of you probably know the command:

WHOAMI /USER /GROUPS

Figure 1: Executing WHOAMI

–

Every wanted to do the same in PowerShell?

[Security.Principal.WindowsIdentity]::GetCurrent())

Figure 2: Executing WHOAMI The PowerShell Equivalent

–

Although it gives you the required information, it still does not list the groups in a nice way. So let’s try that!

Unfortunately not a on-liner, but rather 2 lines of code

–

$tableLayout = @{Expression={((New-Object System.Security.Principal.SecurityIdentifier($_.Value)).Translate([System.Security.Principal.NTAccount])).Value};Label="Group Name";Width=40},@{Expression={$_.Value};Label="Group SID";Width=45},@{Expression={$_.Type};Label="Group Type";Width=75}

([Security.Principal.WindowsIdentity]::GetCurrent()).Claims | FT $tableLayout
