Elixir -- detached pid

For some reason pid of elixir --detached is not equal to $!

For example:

elixir --detached -S mix run --no-halt & echo $!

and

ps aux | grep 'mix run'

outputs different pids.

Is this normal behaviour? I tried nohup, but it has different problems.

I faced with the same problem and found a solution here.
In my case I end up with

$ elixir --detached -e "File.write! 'tmp/pids/bot.pid', :os.getpid" -S mix run --no-halt

$ cat tmp/pids/bot.pid
21352

$ ps aux | grep mix
deployer 21352 50.2  9.1 2234544 45788 ?       Sl   12:21   0:02 /usr/lib/erlang/erts-9.0/b

It might look ugly but it works :)
