I'd recommend reading the Python Tutorial, section "2.1.1 Argument Passing".


#!/usr/bin/python

import sys

for arg in sys.argv:
print arg

What? What do you mean not useful?

The option parser module is excellent.

How about you tell us what you need, and someone (maybe me) will show you how to use the option parser?

For what you mentioned above, something like this would suffice:

from optparse import OptionParser

if __name__ == '__main__':
parser = OptionParser
parser.set_defaults(ntr=0)
parser.add_option("-n", "--ntr", action="store", type=int, help="no idea what this is for")
(options, args) = parser.parse_args()

if len(args) < 1: print "missing file"
filename = args[0]
dest = ''
if len(args) > 1: dest = args[1]

print options.ntr, filename, dest
