Error Handling in PowerShell

 Error Handling in PowerShell

Error handling is used to gracefully handle errors and exceptions in PowerShell scripts. PowerShell supports the try, catch, and finally statements for error handling. Here's an example:

try {

    Get-ChildItem -Path "C:\Windows" -Recurse -ErrorAction Stop

}

catch {

    Write-Host "An error occurred: $($_.Exception.Message)"

}

finally {

    Write-Host "Script complete."

}

In this example, we use the try statement to attempt to list all files and directories in the C:\Windows directory and its subdirectories. We use the -ErrorAction Stop parameter to force PowerShell to throw an error if the command fails. If an error occurs, the catch statement displays an error message. The finally statement is executed regardless of whether an error occurred or not.
