As someone who was used to all users having the same search-path (I'm going back 25 or so years), when I first came across the use of a separate path for the super-user I asked the question "Why?". I have long since answered that question and support the concept. (An aside, can anyone tell me why one of the original grep flags, -y, was changed to -i ?) Perhaps what also needs to be said is that "su <user>" gives the current user the identity of <user> whilst "su - <user>" gives the current user the identity of <user> *along with* <user>'s environment that would normally be obtained by logging in as <user>. I probably haven't expressed the above very well. Looking in my old Unix System V manuals for the su command, I read "An initial - flag causes the environment to be changed to the one that would be expected if the user actually logged in again."
Your explanation is fine, and probably better than mine :)
Perhaps a mention of sudo and sudoers could also be made? Alan.
Good idea - I'll leave that for someone else to add once Ralph/someone gives me an indication where the page should sit.
Thanks for the feedback Alan :) _______________________________________________ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs
