如何在Powershell命令中设置变量

Question

I am trying to declare and set a variable in a powershell command. Is that possible?

I was hoping to do something like this:

"$name" = "I219" | Get-NetAdapter | where Name -Match "$name"

Is this possible or can this only be done in a .ps script?

Answer 1

It can be done easily by just hitting enter in the console after declaring your variable:

$name = "I219" # now hit enter

To access the variable, type it in the console and hit enter again:

$name # hit enter => returns I219

Now use it with your command:

Get-NetAdapter | where { $_.Name -Match $name }

Or as a one-liner:

$name = "I219"; Get-NetAdapter | where { $_.Name -Match $name }
