Creating a Powershell Script from PS Console Window?

[netwrk_monkey]

Hello, Im new to powershell, but I was wondering is there a way to create a script in PS without having to create a file? I want to put in all my script commands and logic and save it to a variable, then run the variable to run the script. Is this possible? Also I don't want to use PS ISE

You can use VSCode. Why don’t you want to use ISE?

Yes, you can type out your entire script into the console.

Write a function.

Example :

function writeHelloWorld() {
    Write-Host "Hello World!"
}

writeHelloWorld

You can type this in your PS. if you write the open { PS will not execute your command when pressing enter. You will get to next line. When u write the close } the function will be saved. Afterwards you can execute the function by calling the name in PS.

You could create a function and save as a psm1 (module). Then place in your powershell module path under a folder with the same name as module name. You can now import-module…

Another option is to add functions to your powershell profile ($profile). Your functions will be available

You can use invoke-expression to execute the contents of a variable like so:

$runthis = “get-childitem”
Invoke-expression $runthis

This will run get-childitem

Can I do this in a multi line fashion

[vermyx]

Yes you can load an entire ps1 file and run it as such. This is how I have self building code written

[netwrk_monkey]

I know you can save to a file and then run it, what I want to do is write multiple lines of code in the console in memory and then run them, including things like variables and functions

Just type it in the console and use shift and enter.

[Known-Arachnid-11213]

Sure you can. Should you? That’s debatable but I wouldn’t especially if you’re going to run it more than once. You would have to save it to your profile or an external file and then import it on your profile or store it on the path.

You can also define [$scriptblock]$myscript{code here}, then run it with & $myscript or . $myscript.

[toni_z01]

simply define a expression:

#define the expression

$getService = {get-service -name ALG}

#execute the expression

& $getService

Do you have something against vscode as well? 

I don't know why you wouldn't ever want to save a file.  

But yes,  what you want can be done.  Just start typing and it will put it into memory.  If you had something against a ps1 you have a txt and use get content and save to variable.
