Standalone Python/Sage Scripts

The tutorial example from

http://doc.sagemath.org/html/en/tutor...

is working only for integers. It does not work for symbolic expressions. It becomes working by renaming the script from "factor" to "factor.sage" and replacing the last line by

print factor(sage_eval(sys.argv[1],locals={'x':x}))

Is there anything wrong in my configuration of Sage?

I got the same, it seems indeed that the symbol x is not injected into the global namespace, but the following works:

./factor "sage.calculus.var.SR.symbol('x')^2+3*sage.calculus.var.SR.symbol('x')"
