most Files in folders such as /etc are belonged root users. but ubunt donn't permit normal users modify it. because the permission of these files are set to 644.
when install some software we may need to modify these files ,here two ways for us to get the permission :
1
# sudo -i
# gedit yourFile
sudo -i command can change user to root in terminal, now you can use all of the command as root users.
when finish editing the file ,remember to close it , the terminal will automatically return to current user.
2
#sudo gedit yourFile
this can open the file with root permission, you can modify it , save it and so on.. when close it ,the terminal also will return to current usr.
