This module allows you to spawn processes, connect to their
input/output/error pipes, and obtain their return codes.
For a complete description of this module see the Python documentation.
Main API
========
run(...): Runs a command, waits for it to complete, then returns a
CompletedProcess instance.
Popen(...): A class for flexibly executing a command in a new process
Constants
---------
DEVNULL: Special value that indicates that os.devnull should be used
PIPE: Special value that indicates a pipe should be created
STDOUT: Special value that indicates that stderr should go to stdout
Older API
=========
call(...): Runs a command, waits for it to complete, then returns
the return code.
check_call(...): Same as call() but raises CalledProcessError()
if return code is not 0
check_output(...): Same as check_call() but returns the contents of
stdout instead of a return code
getoutput(...): Runs a command in the shell, waits for it to complete,
then returns the output
getstatusoutput(...): Runs a command in the shell, waits for it to complete,
then returns a (exitcode, output) tuple

If the exit code was non-zero it raises a CalledProcessError. The
CalledProcessError object will have the return code in the returncode
attribute and output in the output attribute.
The arguments are the same as for the Popen constructor. Example:
>>> check_output(["ls", "-l", "/dev/null"])
b'crw-rw-rw- 1 root root 1, 3 Oct 18 2007 /dev/null\n'
The stdout argument is not allowed as it is used internally.
To capture standard error in the result, use stderr=STDOUT.
>>> check_output(["/bin/sh", "-c",
... "ls -l non_existent_file ; exit 0"],
... stderr=STDOUT)
b'ls: non_existent_file: No such file or directory\n'
There is an additional optional argument, "input", allowing you to
pass a string to the subprocess's stdin. If you use this argument
you may not also use the Popen constructor's "stdin" argument, as
it too will be used internally. Example:
>>> check_output(["sed", "-e", "s/foo/bar/"],
... input=b"when in the course of fooman events\n")
b'when in the course of barman events\n'
By default, all communication is in bytes, and therefore any "input"
should be bytes, and the return value will be bytes. If in text mode,
any "input" should be a string, and the return value will be a string
decoded according to locale encoding, or by "encoding" if set. Text mode
is triggered by setting any of text, encoding, errors or universal_newlines.

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

Translate a sequence of arguments into a command line
string, using the same rules as the MS C runtime:
1) Arguments are delimited by white space, which is either a
space or a tab.
2) A string surrounded by double quotation marks is
interpreted as a single argument, regardless of white space
contained within. A quoted string can be embedded in an
argument.
3) A double quotation mark preceded by a backslash is
interpreted as a literal double quotation mark.
4) Backslashes are interpreted literally, unless they
immediately precede a double quotation mark.
5) If backslashes immediately precede a double quotation mark,
every pair of backslashes is interpreted as a literal
backslash. If the number of backslashes is odd, the last
backslash escapes the next double quotation mark as
described in rule 3.

Execute the string 'cmd' in a shell with 'check_output' and
return a 2-tuple (status, output). The locale encoding is used
to decode the output and process newlines.
A trailing newline is stripped from the output.
The exit status for the command can be interpreted
according to the rules for the function 'wait'. Example:
>>> import subprocess
>>> subprocess.getstatusoutput('ls /bin/ls')
(0, '/bin/ls')
>>> subprocess.getstatusoutput('cat /bin/junk')
(1, 'cat: /bin/junk: No such file or directory')

subprocess requires a posix_spawn() implementation that properly reports
errors to the parent process, & sets errno on the following failures:
* Process attribute actions failed.
* File actions failed.
* exec() failed.
Prefer an implementation which can use vfork() in some cases for best
performance.

communicate() returns a tuple (stdout, stderr).
By default, all communication is in bytes, and therefore any
