An alternative is to use the tail command on Linux and macOS and on windows use Get-Content -Path "path\to\your\file.txt" -Wait (according to ChatGPT). Both via the Deno.Command. You can stream their outputs.

If you weren't using a readable stream and using the other read and write functions on it, then you'd call close to indicate that the file can be released. Otherwise it just hangs around in memory.
