powershell performance log-files PowerShell

I'm building a feature where I'm collaborating on a project where I'm deploying to production and I'm trying to read large log files using `Get-Content` in PowerShell 7.3, but I'm working with important performance optimization and memory consumption... My logs can be several gigabytes in size, and when I attempt to read them, it seems to consume an enormous amount of memory and often leads to the command hanging or failing with an 'Out of Memory' behavior. Here's a snippet of the code I'm using: ```powershell $logFilePath = 'C:\path\to\large.log' $lines = Get-Content -Path $logFilePath -ReadCount 0 foreach ($line in $lines) { # Process each line if ($line -like '*behavior*') { Write-Output $line } } ``` I have tried using `-TotalCount` to limit the number of lines read, but that doesn't help with the performance when trying to process the entire file. I also explored using `-Tail` to get just the recent entries, but I need to analyze the whole log for specific patterns. I've looked into alternatives like using `Select-String` for searching specific patterns, but it still leads to high memory usage when dealing with such large files. Is there a more efficient way to read and process large text files in PowerShell without running into memory issues? I recently upgraded to Powershell 3.10. Am I approaching this the right way? This is my first time working with Powershell 3.11. Thanks for taking the time to read this!
