I need to execute a command and capture the stdout output. I'm overwhelmed by the plethora of means that Python offers to do something like this, and don't know which, if any, is most applicable:
1) the os.system module 2a-d) os.popen, and popen2 popen3 and popen4 3) the popen2 module 4) the subprocess module #1 is synchronous, which is what I want, but it doesn't seem to have any means to capture stdout. #s 2-4 look like they support capturing stdout, but they seem to be asynchronous, which is at the very least overkill for me. I would ideally like something like this: abc = executeit(commandline) or executeit(commandline, abc) where, after execution, abc be a string or list that would contain the output of the command line commandline after its completed. I'm not worried too much about syntax, though; I'd be happy to just find some synchronous command-exeutor that gives me the standard output by any means. More detail, in case it matters: the command line I need to execute is actually three commands, with pipes between them, i.e., string xxxxxxx | grep zzzzzz | head -10 My environment is Python 2.4, Windows/XP (with cygwin installed, hence the availablility of the string, grep and head commands) _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
