There are a few tools and techniques that you can use to troubleshoot problems with PowerShell scripts and commands.  One of the most useful tools for troubleshooting PowerShell scripts is the Set-PSDebug cmdlet, which allows you to enable or disable various debugging options. For example, you can use the -Trace parameter to display verbose output that can help you understand what is happening behind the scenes:  Set-PSDebug -Trace 1  You can also use the -Strict parameter to enable strict mode, which causes PowerShell to generate an error if you use an uninitialized variable or an undefined function:  Set-PSDebug -Strict  Another useful tool for troubleshooting PowerShell scripts is the Write-Debug cmdlet, which allows you to add debugging output to your script. For example:  Write-Debug "This is a debug message"  You can also use the Try/Catch/Finally blocks to handle errors and exceptions in your scripts. For example:  Try {
# code that might throw an exception goes here
} Catch {
# code to handle the exception goes here
} Finally {
# code to execute after the Try block regardless of whether an exception was thrown, goes here
} Finally, you can use the Get-Error cmdlet to display information about the last error that occurred. For example:  Get-Error  These are just a few examples of the tools and techniques that you can use to troubleshoot problems with PowerShell scripts and commands. There are many other options and cmdlets that you can use to diagnose and fix issues in your scripts and commands.
