Effective way to filter on multiple wildcards in PowerShell

Question

I'd like to be able to do

gci -filter *.ps1,*.cs,*.sql

but that syntax isn't supported.

Answer 1

Use -Include which takes an array, instead of -Filter. Note that you have to use * as the path when using -Include:

Get-ChildItem * -Include *.ps1,*.cs,*.sql
