They are:ĭepending on the distribution and shell we are using, the value of this variables can be set permanently in the ~/.bash_profile (only sourced by the bash shell) or the ~/.profile file. The default editor is set via some variables, which are read in a specific order. The temporary file will be opened in the default text editor. The temporary file will be owned by the invoking user, so no administrative privileges will be required in order to modify it. First of all, a temporary copy of the file we want to edit is created. #COTEDITOR TUTORIAL SERIES#When this strategy is used, and the invoking user is permitted to perform the action by the system policy, a series of steps will be performed. As stated in the sudo manual, this option basically means: “edit a file instead of running a command”. Using sudoedit is the equivalent of invoking sudo with the -e option, which is the short for -edit. To solve the problem we illustrated above, we can simply use sudoedit instead of sudo. How can we solve this problem? The solution: using sudoedit The above is just an example and probably our editor customizations go far beyond that. UUID=b308fbe5-68a6-4142-82de-ba1dc3380484 /boot ext2 defaults 1 2Īs you can see line numbers are not displayed. dev/mapper/fingolfin_vg-root_lv / ext4 defaults,vice-timeout=0 1 1 #COTEDITOR TUTORIAL UPDATE## After editing this file, run 'systemctl daemon-reload' to update systemd # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info. # Accessible filesystems, by reference, are maintained under '/dev/disk/'. The content of the file doesn’t matter to us in this case, so it is truncated: # The file will be opened in the editor, and the following is what will be displayed. If we edit the /etc/fstab file invoking the editor directly with sudo, we can see the settings are not effective: $ sudo vim /etc/fstab Say our favorite editor is Vim and in our ~/.vimrc file we entered the set number directive which causes line numbers to be displayed. The customization we set to it (typically via the appropriate dotfiles stored in our HOME directory) will not be honored, since the invoking user environment is not be preserved. If we use our favorite text editor and invoke it directly using sudo, Suppose we must edit a file with administrative privileges, say for example /etc/fstab, which is where the static information about filesystems are stored on Linux. The problem: the editor is launched without user-defined settings This can be rather inconvenient, and in certain cases running an editor with escalated privileges can pose some security issues. In the vast majority of cases, when a command is run with sudo, the invoking user environment is not preserved, so for example, if we invoke our editor using sudo to modify a system file owned by root, it will run ignoring our personal setup. Sudo can be fine-tuned via the /etc/sudoers file since this file is very important, it should be edited using the visudo command, which does ensure no syntax errors are present before changes are saved. #COTEDITOR TUTORIAL FULL#The use of sudo grants us a series of privileges over su, the main one being that specific privileges can be granted to one user without having to give him full root access. The majority of Linux distributions are configured so that the main way to achieve root privileges is to use sudo. $ – requires given linux-commands to be executed as a regular non-privileged user # – requires given linux-commands to be executed with root privileges either directly as a root user or by use of sudo command #COTEDITOR TUTORIAL SOFTWARE#Requirements, Conventions or Software Version Used Software requirements and conventions used Software Requirements and Linux Command Line Conventions Category
