与python的bash交互

请尝试以下示例：

import subprocessproc = subprocess.Popen(['/bin/bash'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)stdout = proc.communicate('ls -lash')print stdout

您必须阅读有关stdin，stdout和stderr的更多信息。看起来不错的演讲：http：//www.doughellmann.com/PyMOTW/subprocess/

另一个例子：

>>> process = subprocess.Popen(['/bin/bash'], shell=False, stdin=subprocess.PIPE, stdout=subprocess.PIPE)>>> process.stdin.write('echo it works!n')>>> process.stdout.readline()'it works!n'>>> process.stdin.write('daten')>>> process.stdout.readline()'wto, 13 mar 2012, 17:25:35 CETn'>>>
