Powershell script to search mutiple remote PC's for specific files - powershell

Question

I am attempting to run a powershell script from my PC against a txt file that contains numerous remote PC's. I want to run a script against that list of PC's that will search a certain file path for specific file name and/or file extension.
I have been attempting to do a for each loop with my txt file inserted as a variable. I am also attempting to get the file names returned to me via the cmdlet "Get-ChildItem."
I have not been able to get anything to work correctly so far. Can anyone point me in the right direction with this? Below are a couple of things I have tried so far...
**
PS C:\Windows\system32> $name= gc env:computername
$computers= get-content -path c:\users\person\Desktop\book2.txt
$csvfile = "c:\temp\$name.csv"
foreach ($computer in $computers) {Get-ChildItem -recurse -filter "C:\Users\*.locky"}
export-csv -filepath $csvfile
**

Answer 1

Wrong -filter parameter in Get-ChildItem cmdlet. Next code snippet should work:
foreach ($computer in $computers) {"\\$computer\C$\Users"|`
Get-ChildItem -recurse -filter "*.locky"}
