Yep, this will happen if you're trying to run the command that way. I suggest you change the file name from factor to factor.sage Notice that you're just adding the extension ".sage" to the end of the original file name. Since Sage is in your path variable, then just do $ sage factor.sage 2006 and you should get the required factorization. This will work regardless of whether or not you set the executable flag for factor.sage. For example, here's my Sage command line session: [mv...@sage ~]$ sage factor.sage 2006 2 * 17 * 59 [mv...@sage ~]$ cat factor.sage #!/usr/bin/env sage -python import sys from sage.all import * if len(sys.argv) != 2: print "Usage: %s <n>"%sys.argv[0] print "Outputs the prime factorization of n." sys.exit(1) print factor(sage_eval(sys.argv[1])) [mv...@sage ~]$ l -gh factor.sage -rw-r--r-- 1 mvngu 226 2009-05-21 05:20 factor.sage > the file content is > > #!/usr/bin/env sage -python > > import sys > from sage.all import * > > if len(sys.argv) != 2: > print "Usage: %s <n>"%sys.argv[0] > print "Outputs the prime factorization of n." > sys.exit(1) > > print factor(sage_eval(sys.argv[1])) > best regards > florian > sorry for the multiple posts (2 times not 3 times...) but the forum > did not show my question and I thought I made something wrong... > regards -- Regards Minh Van Nguyen --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
