JD's original command also used the "bs=2k" option which is equivalent (but not the count option). The dd man page only documents upper-case K for 1024, but I tested and lower-case k works the same. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
