Powershell and sorting listview by linkfilename

Hi,

Does anyone have script example for next situation? :

I've added custom listview in every documentlibrary in sitecollection. Problem is that

now items in list are sorted ascending by "Modified" column. I didn't make this in my previous script.

My customer wants it to be like in "All items" view, where items are sorted ascending by LinkFileName.

I've tried to make one more view with this query without results. Best option would be if i could just update

my previous custom view with this new sorting.

Thanks for any help, I'm stuck in this.
