I use custom powershell functions to make my life easier.
Example:
# custom function > function build {cmd /c build.ps1} # invoke the function > build This works great to allow me to run my build script quickly.
Unfortunately it's easy to forget all of the custom functions that I've created.
Is there a cmdlet that I can run to dump a list of my custom functions? Subsequently, once I know what those functions are, is there a cmdlet that I can run to delete ones that I no longer need?

There are two kinds of functions in PowerShell. We have a “basic” function and an advanced function. “Basic” functions are the simplest form of a function that can be created. They don't have any of the fancy built-in capabilities that advanced functions do.
To make your function available for all users save it in ProgramFiles\WindowsPowerShell\Modules\Gateway. This means, that you have to create a folder there, which has the same name as your file.
Global: The scope that is in effect when PowerShell starts or when you create a new session or runspace. Variables and functions that are present when PowerShell starts have been created in the global scope, such as automatic variables and preference variables.
The “$_” is said to be the pipeline variable in PowerShell. The “$_” variable is an alias to PowerShell's automatic variable named “$PSItem“. It has multiple use cases such as filtering an item or referring to any specific object.
