Need help Creating a Powershell script

Greeting Experts,

I need help creating a script that can scan a list of File Shares (from .txt file) on Microsoft Active Directory Infostructure. The script needs to be able to look the name of files ( with difference file extensions)  and folders that contain keywords in the file name. Then put that into a .csv file with the name of the file, path location, date created, and person username who created it.   The purpose of this script it to quickly search for files file names that contain different keywords (i.e. 4-5 keywords) from a text file. Doing this in manual fashion takes too much time, and records can be missed. Where a script can be more efficient processes. Can somebody help me with this task?..

Could you please provide a step-by-step list of the exact process and does it absolutely have to be a Powershell script?  There may be other simple ways to accomplish what you want.

What is in the .txt file?  UNC paths or server names/IPs?  Where are you going to save the keywords?
Chris DentPowerShell DeveloperCommented:
The following example supports a very simple keyword list. Including things like file extensions will confuse it.
$keywords = (Get-Content yourList.txt) -join '|'
Get-ChildItem C:\Somewhere -Recurse |
    Where-Object BaseName -match $keywords |
    Select-Object Name, FullName, CreationDate, LastWriteTime,
        @{Name='Owner';Expression={ (Get-Acl $_.FullName).Owner }}

It won't be particularly fast for a large structure, and it only supports that list of 4 or 5 keywords. If you had 20 or more keywords the regular expression it generates ($keywords) would become quite unpleasant.
CEOs need to know what they should worry about

Nearly every week during the past few years has featured a headline about the latest data breach, malware attack, ransomware demand, or unrecoverable corporate data loss. Those stories are frequently followed by news that the CEOs at those companies were forced to resign.

Thanks Chris for the script you posted. I tested the script with keywords ( i.e. names of files on my local drive) and used the direct path to my desktop (Win7) and did not output anything.... any ideas....

Does anybody have any suggestions to the following script post above....
Chris DentPowerShell DeveloperCommented:
Sorry, lost track.

I can't find any problems with it. This is my test set.
$keywords = ('powershell', 'powershell_ise') -join '|'

# $keywords = (Get-Content yourList.txt) -join '|'
Get-ChildItem C:\Windows -Recurse |
    Where-Object BaseName -match $keywords |
    Select-Object Name, FullName, CreationDate, LastWriteTime,
        @{Name='Owner';Expression={ (Get-Acl $_.FullName).Owner }}
