Finding all variables and functions in Powershell

To get the list of all the variables or functions that have been declared and pre-existing:

ls variable:*

ls function:*

Note: You can change the wildcard(*) if you are looking for something more specific.

ls can obviously be substituted with dir or get-childitem if you are more familiar with those key-words.

Something Interesting:

If you want to look more closely at what the function is actually doing then you just need to type: $function:<name of function> like so:

$function:mkdir

which will return:

param([string] $name) New-Item $name -type directory
