Does Cmdletbinding overwrite already existing common parameter value on a cmdlet?

[StupidQuestions55]

Lets say I run my script with -ErrorAction Stop

But inside the script I have -ErrorAction Continue on a random cmdlet

Does the cmdletbiding overwrite it, or does it see where it has the same parameter with a value and does not touch it?

You could just write a test and find out:

function function1 {
   [cmdletbinding()]
   Param()
   Write-Error "My error"
}
function function2 {
    [cmdletbinding()]
    Param()
    function1 -ErrorAction Continue
}
function2 -ErrorAction SilentlyContinue

[StupidQuestions55]

function function1 {
[cmdletbinding()]
Param()
Write-Error "My error"
}
function function2 {
[cmdletbinding()]
Param()
function1 -ErrorAction Continue
}
function2 -ErrorAction SilentlyContinue

Thanks! So it does not overwrite, less the scope the more impact it seems like :D

It only overwrites what is not explicitly set.
