Cmd
|
|
-------
|
|
|
|
.. py:function:: pydu.cmd.run(cmd, wait=True, shell=True)
|
|
|
|
Run cmd based on ``subprocess.Popen``.
|
|
If ``wait`` is True, ``run`` will return the tuple of ``(returncode, stdout)``.
|
|
Note, ``stderr`` is redirected to ``stdout``. If ``wait`` is False, ``run``
|
|
will return object of ``Popen``.
|
|
``shell`` is same to parameter of ``Popen``.
|
|
|
|
>>> from pydu.cmd import run
|
|
>>> run('echo hello')
|
|
(0, b'hello\r\n') # Python 3
|
|
>>> run('echo hello', wait=False)
|
|
<subprocess.Popen at 0x22e4010f9e8>
|
|

|
|
|
.. py:function:: pydu.cmd.cmdline_argv()
|
|
|
|
Get command line argv of self python process. On Windows when using Python 2,
|
|
``cmdline_argv`` is implemented by using ``shell32.GetCommandLineArgvW`` to get
|
|
sys.argv as a list of Unicode strings. On other system or using Python 3,
|
|
``cmdline_argv`` is same to ``sys.argv``.
|
|
|
|
There is an example on PyCharm Python Console:
|
|
|
|
>>> from pydu.cmd import cmdline_argv
|
|
>>> cmdline_argv()
|
|
['/Applications/PyCharm.app/Contents/helpers/pydev/pydevconsole.py', '61253', '61254']
|
|
|
|
|
|
.. py:function:: pydu.cmd.chcp()
|
|
|
|
Context manager which sets the active code page number.
|
|
It could also be used as function.
|
|
|
|
>>> from pydu.cmd import chcp
|
|
>>> chcp(437)
|
|
<ctive code page number: 437>
|
|
>>> with chcp(437):
|
|
... pass
|
|
>>>
|
|
|
|
.. note:: ``chcp`` can only be used on ``Windows`` system.
