As of PowerShell 7.1, when using the ExcludeDifferent parameter, IncludeEqual is inferred and the output only contains lines contained in both files, as shown by the. This example uses the ExcludeDifferent parameter to compare each line of content in two text files. will display a grid containing the names of files present in one directory but not in the.
I just tried to the run the script with some logging so I can double check what files are being editied. Example 2 - Compare each line of content and exclude the differences. Not as succinct as I like, but still quite short and quite powerful. $CorrectDatePath="V:\Testing" $InCorrectDatePath="W:\Testing" $FilesWithInCorrectDate='Get-ChildItem $InCorrectDatePath -r | Where-Object | Select-Object Name $IncorrectFile=$I The script should run through and do a check for each file but it is just doing them in one go and not processing them correctly. So far I have written this script below to try and prove this can be done but I can’t get it to work. Building on what you have learned with calculated properties and Get-FileHash, the cmdlet Compare-Object compares the computed hash for each file and outputs any differences.
#Powershell compare files in directory update#
What I am struggling with however is writing a PowerShell script that will find the files of the specific date in one directory and then find the corresponding files in the other directory and then update the dates correctly on the original files. You can compare all files in these folders by generating a hash with Get-FileHash for each file and then comparing them. To change the file date I can just use the below command per file: $a = Get-Item $a.LastWriteTime = $Date
To do this I am trying to write a PowerShell script that will find the files of a specific date () in the one directory and then update the last write time of those files with the date from the corresponding files in the other directory. In this article, Ill start with the easiest yet least precise method to comparing those CEO documents I described earlier. The files in the other directory have the same name. I am trying to change the Last Write time of some files based on the dates of files in another directory.
