Topic: Reading a set number of bytes from a file in basic-cli

I'm trying to read from /dev/urandom, but because it's a virtual, infinite file, the task just hangs. Is there a way in basic-cli to read just a set amount of files from a file or stream?

Not currently. We could implement it.

What would youbexpect the API to be? File.readNBytes or similar?

Yeah, something like that – or if more options are available, then File.readWithOptions { bytes : U64 } or something.
