documentation:
|
--- Executes a command with a new default shell process.
--- The standard I/O streams of the new process (stdin,stdout,stderr)
--- are returned as handles so that they can be explicitly manipulated.
--- They should be closed with `IO.hClose` since they are not
--- closed automatically when the process terminates.
--- @param cmd - the shell command to be executed
--- @return the handles of the input/output/error streams of the new process
