Cmdlet intrepretation of command line args in a function

Given I have a function def like this in my profile:

remove-item alias:dir
function dir {
get-childitem $args | sort-object MshIsContainer -descending
}

I run into trouble if I try to do this:

dir . -Include "*.cs" -Recurse

The function invocation of get-childitem wants to treat each element of args
as a path instead of generic input args. Any ideas on how to get around
this?

 

Yeah - this is broken - $args get's passed as a single element to the inner
command. Unfortunately there really isn't a good workaround. We're
discussing way's of fixing this...

 

Thanks for the heads up. This would be a really good bug to fix otherwise
this workaround for alias's lack of argument pass through winds up pretty
limited.

 

If you require new syntax in order to fix this might I suggest using $* to
represent the arguments to be passed to some command as if they were typed
in at the console. Both KSH and DOSKEY use this syntax for the same thing.

 

One way to work around this for now is to have your function contain the
same arguments as get-childitem.

function dir ([string[]]$path, [string[]]$include, [string[]]$exclude,
[string]$filter, [bool]$recurse)
{
get-childitem -path:$path -include:$include -exclude:$exclude -filter:$filter
-recurse:$recurse | sort-object MshIsContainer -descending
}
