I'm new with Powershell.
There is something that amazes me the way PS works, especially how it retains the variable.
Example:
[string]$a=""
$a = "world"
$b = "Hello $a"
write-host $b
$a = "world2"
write-host $b
The following is what is resulted:
Hello world
Hello world
Why the second write-host does not display "Hello world2"?
Just because when you write $b = "Hello $a" the value of $a is expended and the new string is Hello world.
Like said JPBlanc, you variable is rewrited...
You can do this :
$a = "world"
Set-PSBreakpoint -Variable b -Mode Read -Action { $global:b = "Hello $a" }
write-host $b
$a = "world2"
write-host $b
Or simply use a function:
function SayHello($who){
"Hello $who"
}
$a = "world"
SayHello($a)
$a = "world2"
SayHello($a)
