Powershell edit a variable value

Question

I have a powershell file in which i have a variable named $CurrentReleaseNumber :

$CurrentReleaseNumber="4.5"

What i want to do is edit the value of this variable inside another powershell file. This second powershell file will update the value of this variable and the new value should now reflect in first powershell file. So after execution of second powershell file the first powershell file should look like :

$CurrentReleaseNumber="4.7"

Hi , I have a powershell file having a variable named CurrentReleaseNumber. What I want to do is access this variable inside another powershell file and edit its value. The new value I will receive at run time while running the second powershell file. — tatushar3

Sorry, I still does not understand your goal. Do you want to edit script file, or you doing something else? Please provide expanded sample of what you have, what you have tried, and how current results are different from desired results. And, please, does not do that in comments, edit you question instead. — user4003407

Programming is a fickle thing. Use slightly different terminology and you get entirely different results. Please keep this in mind when asking questions. For example, will you receive these new values before running the second script? Will the first script launch the second? If in doubt, post everything. — Deadly-Bagel

You can try this, it is called dot-sourcing (assuming both files are in the same folder and you are using PS version 3 or higher) :

script1.ps1 :

$myVariable = "hey !"

script2.ps1 :

. "$PSScriptRoot\script1.ps1"

$myVariable

Output :

hey !

@tatushar3 no, it won't, it'll copy them into the current scope

As already said by @PetSerAl, Please provide expanded sample of what you have, what you have tried, and how current results are different from desired results. And, please, does not do that in comments, edit you question instead. Then we will be able to help you further

Your new requirement implies to actually modify the script.ps1 file which is quite different. I don't have a solution for this, and it seems really weird to me : ).
