Linux permission issue

plumb_pete

I am using Ubuntu Linux and am new to Linux. When I try to try to edit some files it requires root privileges. Following command gives a permission error: echo "xyz" > abc.txt But using sudo echo "xyz" > abc.txt works I want to do the same thing from UI. So how can I do it? Also some files like hosts and hostname cannot be edited. Any clues on this? I guess they are read only. How can i make them writable?

Great question — answering as the UphillTech team:

The files appear as read-only because you don't have enough permissions to modify them. If you want to use the GUI, you run your editor from command prompt like: sudo gedit
