Sorry for probably the seemingly dumb question, but I am rather confused on what my professor is asking, or how to test if I got the right answer. I have searched for similar questions but nothing seems to exactly relate.
HI i am a newb when it comes to linux
i am trying to set up an email server but when i try to edit the postfix main.cf file in gedit i can't save it. it says i don't have permissions. root is the only user with read/write permissions. how can i change this or somehow edit the file otherwise?
I just install Ubuntu 12.04. I want to change the boot order of grub. Previous versions of grub.cfg I was able to change the permissions and the do a gedit. After reloading 12.04, I was able to change permissions for grub.cfg, but gedit will not let me save it. I am a little irritated that Ubuntu is suppose to be open source. However someone has chosen to lock one out of a file.
