Delete multiple files on PowerShell command line

You can give PowerShell's rm cmdlet (which is itself an alias for Remove-Item) several files, but you need to separate them with commas.

rm .\subDir\a.png, .\anotherDir\b.jpg, .\thirdDir\c.gif

Check out Get-Help Remove-Item for more details. Or read some documentation on Microsoft's website.

This is what I ended up using:

echo subDir/a.png anotherDir/b.jpg thirdDir/c.gif|rm

This uses echo to pass three string arguments to rm (Remove-Item). I believe this implicitly uses Remove-Item's -Path parameter. The documentation notes that "The parameter name ("-Path") is optional" and it accepts pipeline input by value.
