In Powershell, how do I use Compare-Object based on one property but output all properties?

November 22, 2023

Here is an example of log file inputs which contains MD5 hash and filename (with file size and date time stamp which is fine, what I want).

hashlog1.log:

2E331B30A705D462541398874451A955 \steamapps\appmanifest_1036890.acf 798 20230919_003055

hashlog2.log:

I generate new tables with column headers:

$file1=(Get-Content -Path "hashlog1.log") | Select @{N='Hash'; E={($_ -split ' ',2)[0]}},@{N='File'; E={(($_ -split ' ',2)[1])}}
$file2=(Get-Content -Path "hashlog2.log") | Select @{N='Hash'; E={($_ -split ' ',2)[0]}},@{N='File'; E={(($_ -split ' ',2)[1])}}

I want to compare based on the filename only ("File"). But I would like to output both "Hash" and "File" values in the output.

If I use:

Compare-Object $file1 $file2 -Property File | Select Hash,File,SideIndicator

It seems I should be able to get the proper output but it’s only showing the "File" and "SideIndicator" property values, not "Hash"

Hash File                                                   SideIndicator
---- ----                                                   -------------
     \steamapps\appmanifest_1036890.acf 798 20231122_123455 =>
     \steamapps\appmanifest_1091500.acf 687 20231122_125522 =>
     \steamapps\appmanifest_1036890.acf 798 20230919_003055 <=
     \steamapps\appmanifest_1091500.acf 925 20231026_112000 <=

How do I get it to also output the Hash value as well? Thank you in advance for any assistance.
