function global:Where-DbaObject { <# .SYNOPSIS A slightly more efficient filter function than Where-Object. .DESCRIPTION A slightly more efficient filter function than Where-Object. In case multiple filters are set, any one hit will work. .PARAMETER InputObject The object to process. .PARAMETER PropertyName Whether a property should be tested, rather than the input object itself. .PARAMETER Equals Tests for equality. .PARAMETER NotEquals Tests for inequality. .PARAMETER Like Tests for similarity. .PARAMETER NotLike Tests for non-similarity. .PARAMETER In Tests, whether the input is contained in a specified list. .PARAMETER NotIn Tests, whether the input is not contained in a specified list. .PARAMETER Match Tests for regex match. .PARAMETER NotMatch Tests for regex non-match. .EXAMPLE dir | Where-DbaObject Length -gt 1024 Scans the current folder and filters out all files smaller then 1024 bytes .EXAMPLE "foo","bar" | Where-DbaObject -match "o" Filters out all strings that don't contain the letter "o" #> [CmdletBinding()] param ( [Parameter(ValueFromPipeline = $true, Mandatory = $true)] [object] $InputObject, [Parameter(Position = 0)] [Alias('Property')] [string] $PropertyName, [Alias('Eq')] [object] $Equals, [Alias('Ne')] [object] $NotEquals, [object] $Like, [object] $NotLike, [object] $In, [object] $NotIn, [object] $Match, [object] $NotMatch ) begin { $TestEquals = Test-Bound -ParameterName Equals $TestNotEquals = Test-Bound -ParameterName NotEquals $TestLike = Test-Bound -ParameterName Like $TestNotLike = Test-Bound -ParameterName NotLike $TestIn = Test-Bound -ParameterName In $TestNotIn = Test-Bound -ParameterName NotIn $TestMatch = Test-Bound -ParameterName Match $TestNotMatch = Test-Bound -ParameterName NotMatch $TestObject = -not ($TestEquals -or $TestNotEquals -or $TestLike -or $TestNotLike -or $TestIn -or $TestNotIn -or $TestMatch -or $TestNotMatch) $TestProperty = Test-Bound -ParameterName PropertyName } process { foreach ($item in $InputObject) { #region Test Property if ($TestProperty) { if ($TestObject -and $item.$PropertyName) { return $item } if ($TestEquals -and ($item.$PropertyName -eq $Equals)) { return $item } if ($TestNotEquals -and ($item.$PropertyName -ne $NotEquals)) { return $item } if ($TestLike -and ($item.$PropertyName -like $Like)) { return $item } if ($TestNotLike -and ($item.$PropertyName -notlike $NotLike)) { return $item } if ($TestIn -and ($item.$PropertyName -In $In)) { return $item } if ($TestNotIn -and ($item.$PropertyName -NotIn $NotIn)) { return $item } if ($TestMatch -and ($item.$PropertyName -Match $Match)) { return $item } if ($TestNotMatch -and ($item.$PropertyName -NotMatch $NotMatch)) { return $item } } #endregion Test Property #region Test Object else { if ($TestObject -and $item) { return $item } if ($TestEquals -and ($item -eq $Equals)) { return $item } if ($TestNotEquals -and ($item -ne $NotEquals)) { return $item } if ($TestLike -and ($item -like $Like)) { return $item } if ($TestNotLike -and ($item -notlike $NotLike)) { return $item } if ($TestIn -and ($item -In $In)) { return $item } if ($TestNotIn -and ($item -NotIn $NotIn)) { return $item } if ($TestMatch -and ($item -Match $Match)) { return $item } if ($TestNotMatch -and ($item -NotMatch $NotMatch)) { return $item } } #endregion Test Object } } end { } } (Get-Item Function:\Where-DbaObject).Visibility = "Private" |
