Is it possible to open a shell in a coroutine and just interact with

So in a coroutine, I would just open it and then read and write then
As Dirk wrote, `io.popen` is read XOR write.
If you're on some unix-y system & depending on what you're doing,
lpty might work for you.
There may be "simpler" ways to do that, but so far, for me, this was
the "simplest" way to get non-blocking bidirectional communication going.
(also via `luarocks install lpty`)
 as in "not grabbing a PTY yadda yadda"
 as in "least amount of thinking/code & sufficiently portable (*nix)"
