It has been tested in versions 2, and 5.1 to # reliably provide the same output as the official cmdlet. # # I have added a warning for shells after version 5 to notify the user of the # legacy status of this module, in case it clobbers over the built-in. # # function Get-Uptime { [CmdletBinding( SupportsShouldProcess=$true )] param( [switch]$Since ) begin { $Shell_Version = $PSVersionTable.PSversion.Major $Uptime = @() if ( $Shell_Version -gt 5 ) { Write-Warning "This is a legacy module intended for PowerShell releases prior to version 6." -WarningAction Continue } } process { if ( $Shell_Version -lt 4 ) { $Data_Query = Get-WmiObject -Class Win32_OperatingSystem $Data_Table = $Data_Query.ConvertToDateTime($Data_Query.LocalDateTime) - $Data_Query.ConvertToDateTime($Data_Query.LastBootUpTime) } else { $Data_Query = Get-CimInstance -ClassName Win32_OperatingSystem $Data_Table = $Data_Query.LocalDateTime - $Data_Query.LastBootUpTime } $Uptime = $Data_Table.PSObject.Copy() } end { if ($Since) { if ( $Shell_Version -lt 4 ) { $Data_Query.ConvertToDateTime($Data_Query.LastBootUpTime) } else { $Data_Query.LastBootUpTime } } else { $Uptime } } } New-Alias -Name 'uptime' -Value 'Get-Uptime' |
