tee - Python - How do I split output? -


this question has answer here:

newb python question. i've been reading on tee() , different ways of splitting output. cant find example splitting output terminal , log file. i've been playing around options , have far:

def logname():     env.warn_only = true     timestamp = time.strftime("%d_%b_%y")     return "%s_%s" % (env.host_string, timestamp)  sys.stdout = open('/home/path/to/my/log/directory/%s' % logname(), 'w')

the above log file host name_datestamp won't display on screen. when want stop logging do:

sys.stdout = sys.__stdout__

how can log file definiton above , display terminal @ same time? on right path tee()?

like this?

[user@machine ~]$ python python 2.7.3 (default, aug  9 2012, 17:23:57)  [gcc 4.7.1 20120720 (red hat 4.7.1-5)] on linux2 type "help", "copyright", "credits" or "license" more information. >>> import sys >>>  >>> class tee(object): ...     def __init__(self, logfile, stdio = sys.__stdout__): ...         self.logf = open(logfile, 'w') ...         self.stdio = stdio ...     def write(self, data): ...         self.logf.write(data) ...         self.stdio.write(data) ...     def flush(self): ...         self.logf.flush() ...         self.stdio.flush() ...     def __getattr__(self, k): ...         return getattr(self.stdio, k) ...     def __dir__(self): ...         return dir(self.stdio) ...  >>> sys.stdout = tee('/tmp/output') >>> print 'some test output' test output >>>  [user@machine ~]$ cat /tmp/output  test output [user@machine ~]$
