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 � NZwin32)� monotonicc @ s e Zd ZdS )�SubprocessErrorN)�__name__� __module__� __qualname__� r r �"/usr/lib64/python3.6/subprocess.pyr 9 s r c @ s< e Zd ZdZd dd�Zdd� Zedd� �Zejd d� �ZdS ) �CalledProcessErrorz�Raised when run() is called with check=True and the process returns a non-zero exit status.

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' If universal_newlines=True is passed, the "input" argument must be a string and the return value will be a string rather than bytes. r z3stdout argument not allowed, it will be overridden.�inputN�universal_newlinesF� � T)r r �check)r rr r) r" r )r ro rp r r r r( ; s c @ s* e Zd ZdZd dd�Zdd� Zdd� ZdS ) r+ aE A process that has finished running.

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 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. The other arguments are the same as for the Popen constructor. If universal_newlines=True is passed, the "input" argument must be a string and stdout/stderr in the returned object will be strings rather than bytes.

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)�shellru r r NrF � ���r� )r( r# r r r )r �dataZexitcodeZexr r r r& s c C s t | �d S )a% Return output (stdout or stderr) of executing cmd in a shell.
