Tail a log file and if match trigger an actrion

I am currently using the following line of code to return the most recent line of a log via PowerShell

Get-Content -Path C:\folder\thisisalog.log -Tail 1 -Wait |
    Where {$_ -match "Remote_http"}

This works correctly and will write to the console each time a log that matches "Remote_http" is logged.

However what I would like to do is run another script when this is returned. So far I have tried to add to a variable and check if it is null with no luck and I have tried using if statements with no success. Trying both of these the script runs indefinitely with no output to console or triigers.

I think it may be something to do with -Wait which is causing the issue.

just do it

Get-Content -Path C:\folder\thisisalog.log -Tail 1 -Wait | % {if ($_ -match "Remote_http") {write-host "run code here"}}

or directly into your where

Get-Content -Path C:\folder\thisisalog.log -Tail 1 -Wait | where {if ($_ -match "Remote_http") {write-host "run code here"}}
