compareobject

问题 Quick Question Is there a better (i.e. more efficient / more concise) way to do this? compare-object $a $b | ?{$_.SideIndicator -eq '<='} Detail Compare-Object gives paramenters -excludeDifferent and -includeEqual to allow you to amend which results you get. using both gives you an inner join using just -includeEqual gives you a full outer join using just -excludeDifferent is pointless; as by default equal items are excluded, so it will now exclude everything. There are no options for

问题 I am hashing all the files in one location, an origin folder, and writing the hashes to a variable and then doing the same to all the files in another location, a destination folder: $origin = Get-ChildItem .\Test1 | Get-FileHash | Format-Table -Property Hash -HideTableHeaders $destination = Get-ChildItem .\Test2 | Get-FileHash | Format-Table -Property Hash -HideTableHeaders Then I am comparing them with Compare-Object like so: Compare-Object $origin $destination Now in my test I purposefully

问题 I am building another web server "web2", which must have the same configuration as web server "web1" So after installing some software I need to edit the "web.config" on the "web2" server to match the one in the "web1" server I am doing this from my laptop, so I copied both "web.config" files to my laptop running these commands: $w1="web1.server.local" $w2="web2.server.local" $myCred=(Get-Credential -credential "myAD\myUser") $file="C:\path\to\my\web.config" Invoke-Command -ComputerName $w1

问题 I want to compare 2 text files and output the difference in another text file. compare-object (get-content c:\temp\hostname_old.txt) (get-content c:\temp\hostname_new.txt) | Select-Object -ExpandProperty InputObject | Out-File $Location hostname_old.txt server02 server05 server04 server06 server01 hostname_new.txt (has duplicate names) server04 server01 server02 server04 server02 Result: server04 server02 server05 server06 Note how server04 and server02 are present in this list of differences

问题 I have 2 CSV files with user names. I want to export just the names of users who don't exist in both files. The code I have now: $file1 = import-csv -Path "C:\ps\output\adusers.csv" $file2 = import-csv -Path "C:\ps\output\users.csv" Compare-Object $file1 $file2 -property name | Export-Csv -NoTypeInformation -Path "C:\ps\result\result.csv" 回答1: Use Select-Object name to extract only the name field from Compare-Object's output: Compare-Object $file1 $file2 -Property name | select name | sort

问题 So I'm playing around with Compare-Object, and it works fine for comparing files. But what about just strings? Is there a way to find the difference between strings? CompareTo() is good about reporting that there is a difference, but not what the difference is. For example: PS:> $a = "PowerShell rocks" PS:> $b = "Powershell rocks" PS:> $a.CompareTo($b) 1 PS:> Compare-Object -ReferenceObject $a -DifferenceObject $b PS:> Nothing returned. Any way to let me know about the actual difference

问题 I'm able to diff contents ("cells") of two CSVs and get output of the highest value using the following function: Compare-Object $oldfile $latestfile -Property "UsedSize" -PassThru | select-Object "VolumeName", "UsedSize" | export-csv c:\kits\_write\snapshots\voldelta.csv -NoTypeInfo However, I wish to get the delta/difference between the values in the cells. Is it possible to perform arithmetic to find differences of values in two CSVs? To provide context, we're increasing our NetApp volume

问题 I'm really new to PS and have been cracking my head on a particular problem. I'm trying to get the differences between what is in AD and what SCOM is monitoring already. Based on that I'll run a discovery or push out a look for certain services and if the ports are open. I've been able to build two files for comparison using Get-SCOMAgent and Get-ADComputer and it works like a champ. My problem is that the compare-object is somewhat limited in getting what is present in one file and not in
