Question

Hi,

I have a text file test.txt with the following content:

AAAA z 669
BBBB y 9555
AAAA z 5 
BBBB z 48
CCCC y 1166
AAAA x 67777
BBBB z 223

I want to find lines with "z" and sort the resulting set according to last column.

What I have tried:

Get-Content .\test.txt | Select-String "z" | Sort-Object { [double]$_.split()[-1] }

This gives error:

Sort-Object : Method invocation failed because [Microsoft.PowerShell.Commands.MatchInfo] does not contain a method name
d 'split'.
At line:1 char:46
+ ... test.txt | Select-String "z" | Sort-Object { [double]$_.split()[-1] }
+                                    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidResult: (AAAA z 669:PSObject) [Sort-Object], RuntimeException
    + FullyQualifiedErrorId : ExpressionEvaluation,Microsoft.PowerShell.Commands.SortObjectCommand

Solution 1

Try treating the content like a .csv file and using Import-Csv (Microsoft.PowerShell.Utility) - PowerShell | Microsoft Learn[^] to create a set of custom objects. You should then be able to sort the objects.

[edit]
This seems to work:

PowerShell

$A = Import-Csv -Path .\test.txt -Delimiter " " -Header 'One','Two','Three'
$A | Where-Object -Property Two -Like "z" | Sort-Object { [int]$_.Three }

Note, I used int rather than double since all the values are integral numbers.
