Getting "the system cannot find the file specified. (os error 2)" on Windows

[panstromek]

So I tried to debug this a bit and I found that the offeding line is /src/main:rs::91 :

let _wait = cmd.pipe_to(&[OsStr::new("cat")], &filter_cargo)?;

If I comment it out, it prints the results (seemingly correctly?). At first I though it's because cmd doesn't have cat, but after trying it with powershell (which has cat) or using type (which is Windows equivalent of cat) I still got the same error so now I am bit confused about what's is the real problem.

I am now trying to dig into the pipe_to but I don't actually understand much what's the purpose of that piping there.
