Python to call commands, e.g. "find , perl scripts , nmap , and others" is this possible?

[Emile van Sebille]

Ken,

Are you trying this in IDLE?  I get the same error there.  
If so, try starting python from within a dos window and
see if that makes a difference.  Pipes in winxx are somewhat 
flakey as I understand.

On NT I get: 
>>> mylist = os.popen('dir').readlines() 
Traceback (innermost last): 
  File "<interactive input>", line 1, in ? 
OSError: (0, 'Error') 

(same thing with any command) 

popen (command[, mode[, bufsize]]) 
    Open a pipe to or from command. The return value is an open 
    file object connected to the pipe, which can be read or written 
    depending on whether mode is 'r' (default) or 'w'. The bufsize 
    argument has the same meaning as the corresponding argument 
    to the built-in open() function. The exit status of the command 
    (encoded in the format specified for wait()) is available as the 
    return value of the close() method of the file object, except that 
    when the exit status is zero (termination without errors), None is 
    returned. Availability: Unix, Windows.

  Jim, Take a look at os.popen, as in: import osmylist = os.popen('locate myname').readlines()for eachfile in mylist: do something with eachfile HTH,

  Dear list, 

  I'm new to Python, and I'm sorry if I'm asking about anything that has been 
  already discussed. 

  I would like to use Python to call commands, e.g. "find , perl scripts  , nmap , and others" is this possible? 

  I do not need GUI. All I need is to link the out put and work with it. Is perl or shell scripts my only 
  answer?
