I'm trying to capture the last 15 lines of my terminal output to send over to an AI application. Is there a reliable method for doing this? For instance, I'd like to run something like: `$console = Get-ConsoleBuffer -last 15` and then use that with `aichat.exe -e "Examine last console output: $console do following action on it: $userPrompt"`. I'm planning to wrap this sequence in a function and bind it to a hotkey using PSReadline.

If you just want to capture the output (excluding verbose or error messages), you can use `Command | Select -last 15 | Tee-Object -Variable VariableName`. This way, `$VariableName` will contain just your last 15 lines.
You could highlight the last 15 lines and then right-click to copy them. It's quick, but if you want automation, that’s not gonna cut it!
Right, I’m looking for an automated solution that doesn’t involve manual copying.
If you want to capture output directly to a variable without losing what you see on the terminal, you can do something like: `$VAR = `. Then, to get the last 15 lines out of that, use `Write-Host $VAR` to display it back. This way, you have both.
Just keep in mind that this method won't capture any error messages unless you redirect those too. You can check out the PowerShell documentation on redirection for more details.
That's not exactly what I need; I'm looking for a way to grab the console buffer text directly without manually recording lines.
But I need the console buffer after a command is executed without having to rerun the command each time.
