What are some advanced PowerShell techniques I can use?

You can use techniques like custom functions, error handling, and advanced scripting with modules. What specific area are you interested in?

I'm particularly interested in error handling.

Great! You can use try-catch blocks to handle errors gracefully. Would you like an example?

Yes, please provide an example of using try-catch.

Sure! Here's a simple example:

try {
    Get-Content 'nonexistentfile.txt'
} catch {
    Write-Host 'An error occurred: ' $_.Exception.Message
}

This will catch the error if the file doesn't exist.

That's helpful! How can I log errors to a file instead of just displaying them?

You can modify the catch block to log errors to a file like this:

catch {
    $_ | Out-File 'errorlog.txt' -Append
}

This will append the error details to 'errorlog.txt'.
