Hi, Gopal, I don't want to offend You, but I think You should ask such a questions on "fedora-list" instead of "fedora-laptop-list". As summary on list index says: "Fedora-laptop-list -> Laptop related things" "fedora-list -> Community assistance, encouragement, and advice for using Fedora." Topics You are asking (use of cp, chmod, selinux, shell) are NOT laptop specific. regards, -- jg _______________________________________________ Fedora-laptop-list mailing list Fedora-laptop-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-laptop-list
