Effective way to filter on multiple wildcards in PowerShell

Question:

I’d like to be able to do

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

1 2	gci -filter .ps1,.cs,*.sql

but that syntax isn’t supported.

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

1 2	Get-ChildItem * -Include .ps1,.cs,*.sql
