When importing a module in PowerShell, you may come across the -AllowClobber command option. This option allows you to import a module even if there are conflicting commands or functions already defined in the current session.

1. Press WIN + R, type in powershell, press Ctrl+Shift+Enter. Click OK to run as Administrator.
2. Type powershell into the Taskbar search field. Select Run as Administrator from the list of options in the right panel of the results list.
3. Open the Command Prompt, type powershell, and press Enter. Type start-process PowerShell -verb runas and press Enter.

Transports are used to send events to Sentry. Transports can be customized to some degree to better support highly specific deployments.

Transport

Switches out the transport used to send events. How this works depends on the SDK. It can, for instance, be used to capture events for unit-testing or to send it through some more complex setup that requires proxy authentication.

When it comes to running commands on Windows, PowerShell has become somewhat of an ace in the hole. For years enthusiasts were limited to the confines of the Windows command line but in 2006, PowerShell emerged as a powerful alternative.

1. Press WIN + R, type in powershell, press Ctrl+Shift+Enter. Click OK to run as Administrator.
2. Type powershell into the Taskbar search field. Select Run as Administrator from the list of options in the right panel of the results list.
3. Open the Command Prompt, type powershell, and press Enter. Type start-process PowerShell -verb runas and press Enter.
4. *Also in the Command Prompt, type runas /netonly /user:RemoteDomain\Administrator powershell (substitute a URL or hostname for RemoteDomain)

*A note on option 4 in this list:

These options can be used to hook the SDK in various ways to customize the reporting of events.

BeforeSend

This function is called with an SDK-specific message or error event object, and can return a modified event object, or null to skip reporting the event. This can be used, for instance, for manual PII stripping before sending.

By the time BeforeSend is executed, all scope data has already been applied to the event. Further modification of the scope won’t have any effect.

BeforeBreadcrumb

This function is called with an SDK-specific breadcrumb object before the breadcrumb is added to the scope. When nothing is returned from the function, the breadcrumb is dropped. To pass the breadcrumb through, return the first argument, which contains the breadcrumb object. The callback typically gets a second argument (called a “hint”) which contains the original object from which the breadcrumb was created to further customize what the breadcrumb should look like.

EnableTracing

A boolean value, if true, transactions and trace data will be generated and captured. This will set the traces-sample-rate to the recommended default of 1.0 if traces-sample-rate is not defined. Note that traces-sample-rate and traces-sampler take precedence over this option.

TracesSampleRate

A number between 0 and 1, controlling the percentage chance a given transaction will be sent to Sentry. (0 represents 0% while 1 represents 100%.) Applies equally to all transactions created in the app. Either this or TracesSampler must be defined to enable tracing.

TracesSampler

A function responsible for determining the percentage chance a given transaction will be sent to Sentry. It will automatically be passed information about the transaction and the context in which it’s being created, and must return a number between 0 (0% chance of being sent) and 1 (100% chance of being sent). Can also be used for filtering transactions, by returning 0 for those that are unwanted. Either this or TracesSampleRate must be defined to enable tracing.

SDKs are configurable using a variety of options. The options are largely standardized among SDKs, but there are some differences to better accommodate platform peculiarities. Options are set when the SDK is first initialized.

For example, initialize with Start-Sentry in your PowerShell script:

    # A Sentry Data Source Name (DSN) is required.
    # See https://docs.sentry.io/product/sentry-basics/dsn-explainer/
    # You can set it in the SENTRY_DSN environment variable, or you can set it in code here.
    # When debug is enabled, the Sentry client will emit detailed debugging information to the console.
    # This might be helpful, or might interfere with the normal operation of your application.
    # We enable it here for demonstration purposes when first trying Sentry.
    # You shouldn't do this in your applications unless you're troubleshooting issues with Sentry.
    # Alternatively, you can pass `-Debug` to the `Start-Sentry` command.
    Debug = 
    # This option is recommended. It enables Sentry's "Release Health" feature.
    AutoSessionTracking = 
    # This option will enable Sentry's tracing features. You still need to start transactions and spans.
    # Example sample rate for your transactions: captures 10% of transactions
    TracesSampleRate = 01

For instance, to get all network addresses/adapters in order to apply settings to them:

Get-NetIPAddress | Set-NetIPAddress -SkipAsSource $true

I know I can use if, Where-Object, or whatever, but the point is to do it shortly like you can do in Bash with just !. This is why I phrased it as negating options rather than conditions.

Get-NetIPAddress -ifIndex !39
Get-NetIPAddress -ifIndex -ne 39
Get-NetIPAddress (! -ifIndex 39)
Get-NetIPAddress !(-ifIndex 39)
Get-NetIPAddress -ifIndex not 39

I wasn’t expecting them to work since, some of them are borrowed syntax from the other functions(?). You don’t bother typing the command without a little bit of hope it’ll work though.

The standard PowerShell option parser does not have a generic “negation” syntax because it’s an option parser, not a filter parser (even if some the options happen to be used for the purpose of filtering, but that happens long after the options and their values been parsed) – boolean “flag” options can be negated, but “value” options cannot.

(You can’t really do it in “Bash” either; find ! -foo only works because the find command specifically uses a custom command-line parser that has been designed for that, but this does not apply to any other program, certainly not the ones using a generic getopt_long --option parser.)

The cmdlet could recognize ! as part of the option value (e.g. Get-NetIPAddress -ifIndex !39), but again, hasn’t been programmed that way. (It probably requests ifIndex to be parsed as an integer.)

PowerShell does accept the ! operator as a alternative syntax
for the not operator, although only in the context of a boolean
expression, so not with parameters.

For example, you may write :

if (-Not (Test-Path C:\Code)) {
    write "it doesn't exist!"
} 

But you may also use ! this way:

if (!(Test-Path C:\Code)) { write "it doesn't exist!" }

The list of common options across SDKs. These work more or less the same in all SDKs, but some subtle differences will exist to better support the platform. Options that can be read from an environment variable (SENTRY_DSN, SENTRY_ENVIRONMENT, SENTRY_RELEASE) are read automatically.

Dsn

The DSN tells the SDK where to send the events. If this value is not provided, the SDK will try to read it from the SENTRY_DSN environment variable. If that variable also does not exist, the SDK will just not send any events.

In runtimes without a process environment (such as the browser) that fallback does not apply.

IsGlobalModeEnabled

Specifies whether to use global scope management mode. Should be true for client applications and false for server applications.

Defaults to true for PowerShell.

Debug

Turns debug mode on or off. If debug is enabled SDK will attempt to print out useful debugging information if something goes wrong with sending the event. The default is always false. It’s generally not recommended to turn it on in production, though turning debug mode on will not cause any safety concerns.

DiagnosticLevel

Enabling debug mode makes the SDK generate as much diagnostic data as possible. However, if you’d prefer to lower the verbosity of the Sentry SDK diagnostics logs, configure this option to set the appropriate level:

• debug: default The most verbose mode
• info: Informational messages
• warning: Warning that something might not be right
• error: Only SDK internal errors are printed
• fatal: Only critical errors are printed

Dist

Sets the distribution of the application. Distributions are used to disambiguate build or deployment variants of the same release of an application. For example, the dist can be a hash of the script file contents. The dist has a max length of 64 characters.

Release

By default the SDK will try to read this value from the SENTRY_RELEASE environment variable (in the browser SDK, this will be read off of the window.SENTRY_RELEASE.id if available).

Environment

Sets the environment. This string is freeform and set by default. A release can be associated with more than one environment to separate them in the UI (think staging vs prod or similar).

By default, the SDK reports debug when the debugger is attached. Otherwise, the default environment is production.

SampleRate

Configures the sample rate for error events, in the range of 0.0 to 1.0. The default is 1.0, which means that 100% of error events will be sent. If set to 0.1, only 10% of error events will be sent. Events are picked randomly.

This variable controls the total amount of breadcrumbs that should be captured. This defaults to 100, but you can set this to any number. However, you should be aware that Sentry has a maximum payload size and any events exceeding that payload size will be dropped.

MaxCacheItems

AttachStacktrace

When enabled, stack traces are automatically attached to all messages logged. Stack traces are always attached to exceptions; however, when this option is set, stack traces are also sent with messages. This option, for instance, means that stack traces appear next to all log messages.

Grouping in Sentry is different for events with stack traces and without. As a result, you will get new groups as you enable or disable this flag for certain events.

SendDefaultPii

If this flag is enabled, certain personally identifiable information (PII) is added by active integrations. By default, no such data is sent.

This option is turned off by default.

If you enable this option, be sure to manually remove what you don’t want to send using our features for managing Sensitive Data.

SendClientReports

Set this boolean to false to disable sending of client reports. Client reports are a protocol feature that let clients send status reports about themselves to Sentry. They are currently mainly used to emit outcomes for events that were never sent.

How do I learn bash scripting?

Bash scripting is a Unix shell script. As Linux is an adaptation of Unix, a shell script written for Linux is often called a Bash script. There are a lot of online tutorials on how to create a Bash script. In order to avoid confusion, try not to refer to a PowerShell script as a Bash script.

How to Use Windows PowerShell

Udemy has a number of top-rated courses on PowerShell that you might find useful.

What is the -AllowClobber Command Option?

The -AllowClobber command option is used with the Import-Module cmdlet in PowerShell. By default, when you import a module, PowerShell checks if there are any conflicting commands or functions already defined in the current session. If conflicts are found, PowerShell will not import the module and will display an error message.

However, by using the -AllowClobber command option, you can override this behavior and allow the module to be imported even if there are conflicting commands or functions. This can be useful in certain scenarios where you want to use a specific version of a command or function provided by a module, even if there is a conflicting version already defined in the session.

How can I make Command Prompt default instead of PowerShell?

When you press WIN + X, you now get a PowerShell window instead of the old Command Prompt. To stick with Command Prompt, go to the Start menu and click on Settings. In the Settings menu, select Personalization. Select Taskbar in the left-hand menu of the Personalization Settings Window. In the main panel of that window, look for Replace Command Prompt with Windows PowerShell in the menu when I right-click the Start button or press Windows key+X. Set that to Off.

The Essential PowerShell Commands

Using aliases will only get you so far on PowerShell, so it’s important to commit to learning everything you can about PowerShell’s native commands. We touched on some of these above, but we’re going to break down the main ones in much more detail below.

Get-Help

For example, if you wanted to see how Get-Process works, you would type:

PS C:\> Get-Help -Name Get-Process

PS C:\> Set-ExecutionPolicy

As touched on earlier in this guide, Microsoft has a restricted execution policy that prevents scripting on PowerShell unless you change it. When setting the execution policy, you have four options to choose from:

• Restricted – The default execution policy that stops scripts from running.
• All Signed – Will run scripts if they are signed by a trusted publisher
• Remote Signed – Allows scripts to run which have been created locally
• Unrestricted – A policy with no restrictions on running scripts

PS C:\> Get-ExecutionPolicy

If you’re using PowerShell, you may not always work on a server that you’re familiar with. Running the command Get-Execution Policy will allow you to see which policy is active on the server before running a new script. If you then see the server in question operating under a restricted policy, you can then implement the Set-ExecutionPolicy command to change it.

Get-Service

For example, if you were to type PS C:\> Get-Service, you would be shown a list of all services on your computer, their statuses, and display names.

To use this command to retrieve specific services, type:   PS C:\ Get-Service “WMI*” to retrieve all services that begin with WMI.

PS C:\ Get-Service | Where-Object {$_.Status -eq “Running”}

ConvertTo-HTML

When using PowerShell, you might want to generate a report about the information you’ve seen. One of the best ways to do this is by using the ConvertTo-HTML command. This cmdlet allows you to build reports with tables and color, which can help to visualize complex data. Simply choose an object and add it to the command.

For example, you could type:

Get-PSDrive | ConvertTo-Html

This returns a mass of information, so it’s a good idea to limit it to a file with the Out-File command. A better alternative command is:

Get-PSD Drive | ConvertTo-Html | Out-File -FilePath PSDrives.html

This will then generate an HTML file in table form. For example:

You can then add your own colors and borders to refine its presentation.

Export-CSV (and Get-Service)

To use this command, you would type:

PS C:\> Get-Service | Export-CSV c:\service.csv

It’s important to remember not to format objects before running the Export-CSV command. This is because formatting objects results in only the formatted properties being placed into the CSV file rather than the original objects themselves. In the event that you want to send specific properties of an object to a CSV file, you would use the Select-Object cmdlet.

To use the Select-Object cmdlet, type:

PS C:\> Get-Service | Select-Object Name, Status | Export-CSV c:\Service.csv

Get-Process

If you want to view all processes currently running on your system, the Get-Process command is very important. To get a list of all active processes on your computer, type:

PS C:\ Get-Process

Notice that if you don’t specify any parameters, you’ll get a breakdown of every active process on your computer. To pick a specific process, narrow the results down by process name or process ID and combine that with the Format-List cmdlet, which displays all available properties. For example:

PS C:\ Get-Process windowrd, explorer | Format-List *

This provides you with comprehensive oversight of all active processes.

Get-EventLog

If you ever want to access your computer’s event logs (or logs on remote computers) while using PowerShell, then you’re going to need the Get-EventLog command. This cmdlet only works on classic event logs, so you’ll need the Get-WinEvent command for logs later than Windows Vista.

To run the event log command, type:

PS C:\> Get-EventLog -List

This will show all event logs on your computer.

PS C:\> Get-EventLog -LogName System -EntryType Error

If you want to get event logs from multiple computers, specify which devices you want to view (listed below as “Server1” and “Server2”). For example:

PS C:\> Get-EventLog - LogName “Windows PowerShell” -ComputerName “local computer”, “Server1”, “Server2”.

 Stop-Process

When using PowerShell, it’s not uncommon to experience a process freezing up. Whenever this happens, you can use Get-Process to retrieve the name of the process experiencing difficulties and then stop it with the Stop-Process command.

Generally, you terminate a process by its name. For example:

PS C:\> Stop-Process -Name “notepad”

Overlap with Windows Commands

Much like Command Prompt, on PowerShell the cd command still changes directories, and dir still provides a list of files within the selected folder. As such, it’s important to remember you aren’t necessarily starting from scratch. Taking this on board will help to decrease the learning curve you face when using PowerShell and decrease the number of new commands that you have to learn.

Here are some commands that are common to PowerShell and Windows:

• cd: Change Directory. This command is used to change the current working directory. In PowerShell, Set-Location can be used as well.
• cls: Clear Screen. This command clears the screen of the console. In PowerShell, Clear-Host or its alias cls can be used.
• dir: Directory. This command lists the files and subdirectories in the directory. In PowerShell, Get-ChildItem can be used as well.
• echo: This command prints text to the console. In PowerShell, Write-Output can be used as well.
• copy: This command copies files. In PowerShell, Copy-Item can be used as well.
• del: Delete. This command deletes one or more files. In PowerShell, Remove-Item can be used as well.
• move: This command moves files from one location to another. In PowerShell, Move-Item can be used as well.
• type: This command displays the contents of a text file. In PowerShell, Get-Content can be used as well.
• find: This command searches for a text string in a file. In PowerShell, Select-String can be used as well.
• exit: This command closes the command prompt or terminal window. It works the same in both Command Prompt and PowerShell.

Is Windows PowerShell the same as Command Prompt?

PowerShell is an advancement on Command Prompt because its shell scripting capabilities include better programming constructs than those available for batch jobs in Command Prompt. All of the Command Prompt commands are available in PowerShell but then PowerShell has extra commands and utilities, called cmdlets. Think of PowerShell as Command Prompt +.

Backing Up an SQL Database with PowerShell

Many people use PowerShell to back up SQL databases. The command-line interface can conduct full database backups, file backups, and transaction log backups. There are many ways to backup a database in PowerShell, but one of the simplest is to use the Backup-SqlDatabase command. For example:

PS C:\> Backup-SqlDatabase -ServerINstance “Computer\Instance” -Database “Databasecentral”

This will create a database backup of a database with the name ‘Databasecentral’ (or the name of your chosen database’.

To back up a transaction log, you would input:

PS C:\> Backup-SqlDatabase -ServerInstance “Computer\Instance”  -Database “Databasecentral” -BackupAction Log

This will create a transaction log of the selected database.

Loading Up PowerShell

Before we delve into the basics of using PowerShell, you first need to access the main interface.

How to Run cmdlets

In a nutshell, a cmdlet is a single-function command. You input cmdlets into the command line just as you would with a traditional command or utility. Cmdlets are the main way to interact with the CLI.

In PowerShell, most cmdlets are written in C# and comprised of instructions designed to perform a function that returns a .NET object.

Over 200 cmdlets can be used in PowerShell. Windows PowerShell command prompt isn’t case-sensitive, so these commands can be typed in either upper or lower case. The main cmdlets are listed below:

• Get-Location – Get the current directory
• Set-Location – Get the current directory
• Move-item – Move a file to a new location
• Copy-item – Copy a file to a new location
• Rename – item Rename an existing file
• New-item – Create a new file

PS C:\> Get-Command

PS C:\>   Set-ExecutionPolicy

PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

How do I run PowerShell commands?

You can run PowerShell commands from a Command Prompt window by using the format: powershell -command ” <PowerShellCode> “ but put your PowerShell command inside the quotes instead of <PowerShellCode>. If your PowerShell command requires a value in quotes, use single quotes in there instead of double-quotes. The surrounding quotes in the execution example here should remain as double-quotes.

When to Use the -AllowClobber Command Option

There are a few scenarios where you might want to use the -AllowClobber command option:

• Using a Specific Version: If you have a module that provides a command or function that has been updated or modified, but you still want to use a specific version of that command or function, you can use the -AllowClobber command option to import the module and override any conflicting versions.
• Testing and Troubleshooting: When troubleshooting or testing a script or module, you may want to import a module even if there are conflicting commands or functions in the current session. This can help you isolate and identify any issues or conflicts that may arise.
• Customizing Functionality: In some cases, you may want to customize the functionality of a command or function provided by a module. By importing the module with the -AllowClobber command option, you can define your own version of the command or function and override any conflicting versions.

How to Use the -AllowClobber Command Option

To use the -AllowClobber command option, you need to include it when importing a module using the Import-Module cmdlet. Here is the syntax:

Import-Module -Name <ModuleName> -AllowClobber

Replace <ModuleName> with the name of the module you want to import. By including the -AllowClobber command option, you are explicitly allowing the module to be imported even if there are conflicting commands or functions.

It’s important to note that using the -AllowClobber command option can have unintended consequences if not used carefully. It can potentially overwrite or override existing commands or functions in the current session, which may lead to unexpected behavior or errors. Therefore, it’s recommended to use this command option with caution and only when necessary.

How to Run PowerShell Scripts

Script-based processes and commands are part of the foundation of PowerShell’s versatility. In PowerShell, a script is essentially a text file with a ps1 extension in its filename. To create a new script you can simply open the Windows notepad, type your commands, and save with ‘.ps1’ at the end of the name.

To run a script, enter its folder and filename into the PowerShell window:

PS c:\powershell\mynewscript.ps1

Once you’ve done this, your selected script will run.

Conclusion

The -AllowClobber command option in PowerShell provides the flexibility to import modules even if there are conflicting commands or functions in the current session. It allows you to use specific versions of commands or functions, troubleshoot and test scripts, and customize functionality. However, it’s important to exercise caution when using this command option to avoid any unintended consequences. Always ensure that you understand the potential impact before using the -AllowClobber command option in PowerShell.
