Why this PowerShell alias does not work?

I am learning PowerShell.

I would like to understand why some aliases in PowerShell 5.0 under Windows 8.1 do not work.

For instance, this command alone works:

Get-WmiObject -Class Win32_WinSAT

But it does not when defined in my $profile as follows:

Set-Alias -Name wei -Value 'Get-WmiObject -Class Win32_WinSAT'

The error message follows:

PS C:> wei

wei : The term 'Get-WmiObject -Class Win32_WinSAT' is not recognized as the 

name of a cmdlet, function, script file,

or operable program. Check the spelling of the name, or if a path was 

included, verify that the path is correct and

try again.

At line:1 char:1

+ wei

+ ~~~

    + CategoryInfo          : ObjectNotFound: (Get-WmiObject -Class Win32_WinSAT:String) , CommandNotFoundException

    + FullyQualifiedErrorId : CommandNotFoundException

EDIT:

I see the aliases work a little different than in standard Bash on Linux I am used to.

The solution was to simply declare it as a function:

Function wei { Get-WmiObject -Class Win32_WinSAT }

Your alias equivalent to & 'Get-WmiObject -Class Win32_WinSAT'.

Normally PowerShell tries to use the first space to separate the command from the parameters. However, you can use a string to specify that a space is just part of a file. This essentially lets you treat the space like a non-special character, and allows you to treat something like 'C:Program FilesWindows NTAccessoriesnotepad.exe' as if it was one word, not two.

That's essentially what you're doing. PowerShell cannot find a command named 'Get-WmiObject -Class Win32_WinSAT', because there is no such command. (The command in question is simply 'Get-WmiObject', not 'Get-WmiObject -Class Win32_WinSAT'.

So, I have now identified the problem. I realize I haven't provided a workaround/solution. Being that I am supposed to be at work in less than 5 hours and should get some more sleep before then, I will allow someone else that pleasure. Hopefully my comment helped identify the right track of what needed to be solved.

If you like to pass other parameters to your alias, you can do this:

function wei([Parameter(ValueFromRemainingArguments = $true)]$params) {

    & Get-WmiObject -Class Win32_WinSAT $params

}
