How to search a word in a file using PowerShell script

问题

I have a list of 350 folders and each folder has a file Access log. I need to search all 350 files under all 350 folders for a name "Hound" and display the name of the folders which contain the name "Hound" in their access log file. Below is my code, can someone help me with what should be added here to get the desired output, please?

   #List all the folders in C:\testfolder
   $folders = (Get-ChildItem -Path "C:\testfolder" | Where-Object{$_.Attributes -eq "Directory"} | Select Fullname)

   #looping all folders
   Foreach ($folder in $folders)
   {

   #Here I need to look for the word "Hound" inside the Access.log file and if the word is there, it should display the name of the $folder which has the word
   }

回答1:

Here's a fairly basic way to do this:

Get-ChildItem -Path d:\testfolder -Recurse | Select-String -Pattern "Hound"

If you need to make sure that only files called access.log are searched then specify a filter:

Get-ChildItem -Path d:\testfolder -Include "access.log" -Recurse | Select-String -Pattern "Hound"
