The PowerShell Integrated Console starts on demand when you first open/activate an editor with PowerShell code in a session, and it shows as follows in the integrated terminal's toolbar: They show by their executable file name in the dropdown list in the integrated terminal's toolbar e.g.:īy contrast, the PowerShell Integrated Console is a special shell that comes with the PowerShell extension and offers integration with PowerShell code being edited, notably to provide linting and debugging support, among other features.

Shells that run in the integrated terminal by default have no special integration with the files being edited.

VSCode ( Visual Studio Code) has an integrated terminal (console) that can run any shell, such as cmd.exe, bash, or pwsh or powershell.

Windows PowerShell comes with Windows itself, whereas PowerShell must be installed on demand (on all supported platforms).NET 5+ by contrast, powershell.exe is the executable name of the legacy Windows PowerShell edition (v5.1-), built on the Windows-only. Hope this gives an idea on when to use what.Pwsh is the executable file name of PowerShell (v6+), the cross-platform edition of PowerShell built on.

To avoid this drawback and to keep any changes made to global variables you can dot the script which will always execute the script in your current scope.ĭot sourcing will only run the function or script within the current scope and call operator ( &) which will run a function or script as usual but it will never add to the current scope. If the command is changing any of the values in a global variable then in that case the changes will be lost when the scope ends as well. Invoking a command (either directly or with the call operator) will create another scope known as child scope and will be gone once the command been executed. Whereas, & is the call operator in Powershell which will help you to call any of the outside executable like psexec and others. So you are using the function which is present in source.ps1 in your custom script. Put a line in M圜ustomScript.ps1 like the below and you should be able to use it. And you wish to use that function in another script( M圜ustomScript.ps1) Imagine you have function named MyFunction in a source.ps1. To segregate and give a clear understanding, I am explaining a scenario.

That said, functions defined in modules aren't usually designed with dot-sourcing in mind anyway.

with a module-originated function is virtually pointless, because the scope getting modified is the module's. current is not necessarily the caller's scope: if the function was defined in a module, the reference scope is that module's scope domain: The caveat is that for functions (as opposed to scripts) the reference scope for child vs. For instance, this mechanism is used to load the $PROFILE file that initializes an interactive session. , the dot-sourcing operator, executes scripts and functions in the current scope and is typically used to modify the caller's scope by adding functions, aliases, and possibly variables for later use. ) or the global scope ( $global.) or defining process-level environment variables.

Note, however, that even a script run in a child scope can affect the caller's environment, such as by using Set-Location to change the current location, explicitly modifying the parent scope ( Set-Variable -Scope 1. The variables, (nested) functions, aliases defined in the script / function invoked are local to the invocation and go out of scope when the script exits / function returns. &, the call operator, executes scripts and functions in a child scope, which is the typical use case: functions and scripts are typically expected to execute without side effects: and & differ with respect to scoping of the definition of functions, aliases, and variables: and & operators matters only when calling PowerShell scripts or functions (or their aliases) - for cmdlets and external programs, they act the same.įor scripts and functions.
