- all commands are checked at 'from sh import' time so they are guaranteed to exist
- Always use `_err=sys.stderr` ou `_err_to_out=True` because default is to discard commands stderr
- `print()` is NEEDED to display command output (or you need to use `_out=sys.stdout`)
- `_piped='direct'` is useful to connect processes without consuming any memory
- `_iter` : creates a line generator => you can chain lazy functions taking a 'input_iterator' as input & output
- a command invocation return a `RunningCommand` object, on which you can wait for the text output (by calling `str()` on it)
or get a list of output lines (by calling `list()` on it)
