You don't need to `foreach { Remove-Item $_.Name }` because Remove-Item can take the objects returned by Get-ChildItem directly.
Also, expanding the regex into `-Include` parameters is somewhat cheating since `-Include` only takes globs, and it just so happens that that particular regex can be converted into globs.
The general equivalent is:
gci -re | ?{ $_.Name -match '.*_test\.(py|cc)' } | ri
(I used the shorter aliases because someone will probably read yours and reinforce the stereotype that PS is overly verbose.)
Thanks, this is definitely closer to the original use of `egrep`! As for aliases, I prefer long forms because I don't need to think what the seemingly random collections of letters mean, and tab-completion / PowerShell ISE makes it mostly a non-issue when writing.
