In the case of `commanda | commandb`, the `STDOUT` of `commanda` is used as `STDIN` for `commandb`. In the case of `commanda |& commandb`, the `STDOUT` and `STDERR` of `commanda` are used as `STDIN` for `commandb`. In either case, each command is executed in a subshell, and the exit code is set according to the final command. ---- CategoryRicottone
