communicate	Interact with process: Send data to stdin and close it.
kill	Kill the process with SIGKILL
poll	Check if child process has terminated.
send_signal	Send a signal to the process.
terminate	Terminate the process with SIGTERM
wait	Wait for child process to terminate; returns self.returncode.

Attributes

pid
returncode

__init__(cmd, **kwargs)

Create new Popen instance.

communicate(input=None, timeout=None)

Interact with process: Send data to stdin and close it. Read data from stdout and stderr, until end-of-file is reached. Wait for process to terminate.

The optional “input” argument should be data to be sent to the child process, or None, if no data should be sent to the child. communicate() returns a tuple (stdout, stderr).

By default, all communication is in bytes, and therefore any “input” should be bytes, and the (stdout, stderr) will be bytes. If in text mode (indicated by self.text_mode), any “input” should be a string, and (stdout, stderr) will be strings decoded according to locale encoding, or by “encoding” if set. Text mode is triggered by setting any of text, encoding, errors or universal_newlines.

kill()

Kill the process with SIGKILL

poll()

Check if child process has terminated. Set and return returncode attribute.

send_signal(sig)

Send a signal to the process.

terminate()

Terminate the process with SIGTERM

wait(timeout=None, _interval: float = 0.05)

Wait for child process to terminate; returns self.returncode.
