There are aliases for parameters, `-ea` for `-ErrorAction` comes to mind. But those are defined by cmdlets, not the user.

However, you can always shorten parameter names as long as they remain unambiguous with other parameters, so

    Get-ChildItem -Recurse -Include foo

would become

    ls -r -i foo

which just happens to be shorter than your 'find' example.
