instance.
470s
470s The returned instance will have attributes args, returncode,
stdout and
470s stderr. By default, stdout and stderr are not captured, and those
attributes
470s will be None. Pass stdout=PIPE and/or stderr=PIPE in order to
capture them,
470s or pass capture_output=True to capture both.
470s
470s If check is True and the exit code was non-zero, it raises a
470s CalledProcessError. The CalledProcessError object will have the
return code
470s in the returncode attribute, and output & stderr attributes if
those streams
470s were captured.
470s
470s If timeout is given, and the process takes too long, a
TimeoutExpired
470s exception will be raised.
470s
470s There is an optional argument "input", allowing you to
470s pass bytes or a string to the subprocess's stdin. If you use this
argument
470s you may not also use the Popen constructor's "stdin" argument, as
470s it will be used internally.
470s
470s By default, all communication is in bytes, and therefore any
"input" should
470s be bytes, and the stdout and stderr will be bytes. If in text
mode, any
470s "input" should be a string, and stdout and stderr will be strings
decoded
470s according to locale encoding, or by "encoding" if set. Text mode is
470s triggered by setting any of text, encoding, errors or
universal_newlines.
470s
470s The other arguments are the same as for the Popen constructor.
