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

So for multiple filters, there's really no way to reap the performance advantage of -filter over -include? – noam Dec 06 '12 at 23:23
That asterisk is a real gotcha. – jim birch Nov 25 '21 at 00:38

With v3, can do gci -file "*.ps1","*.txt"

This too wants the path to be the current directory, but push-location seems to offer a viable workaround. I'm beginning to suspect that -file performs more like -include as opposed to the faster -filter. – noam Dec 07 '12 at 00:15

`-file` is a switch parameter and doesn't accept values! "*.ps1","*.txt" are passed as values for parameter `-path`. Your command is equivalent to do `gci -path "*.exe","*.xml"` but only excude eventualy directory with name endinf with `.ps1` or `.txt` – CB. Dec 07 '12 at 21:35
