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.

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.

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.

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.

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.getstatusoutput('/bin/junk') (127, 'sh: /bin/junk: not found') >>> subprocess.getstatusoutput('/bin/kill $$') (-15, '') T)�shellr� r. r Nr_ � )r r r r- r+ )r, �data�exitcode�exr' r' r( r ^ s r c C s t | �d S )a% Return output (stdout or stderr) of executing cmd in a shell.

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.
