powershell - In PowerShell, is it possible to create an alias whose name has a space in it?

Question

I want to make rm -rf an alias for Remove-Item, since I keep accidentally typing it when using PowerShell.

I had guessed maybe I could do something like this, but that doesn't work.

Set-Alias -name 'rm -rf' -value Remove-Item

You could also remove the default alias and then replace it with a custom function.

# remove default alias
if (Test-Path Alias:rm) {
    Remove-Item Alias:rm
}

# custom function for 'rm'
function rm {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory = $false)]
        [switch]$rf,

        [Parameter(Mandatory = $true, ValueFromPipeline = $true)]
        [string]$Path
    )
    process {
        Remove-Item -Path $Path -Recurse:$rf -Force:$rf
    }
}

Then call it like this:

rm -rf "C:\Temp\dir"

If course, so far this function doesn't have the full functionality of Remove-Item, but you can extend it as you like.

Note: Even though this "solves" your problem in the short-run, you should not revert to these kinds of workarounds. Better get accustomed to the actual PowerShell commands and syntax, or you're bound to run into more problems sooner or later.
