I’m trying to update my grub boot order back to booting the first option instead of the second, so I run sudo nano /etc/default/grub
, but it brings up this, which is not the file I want to edit.
I’m on fedora 38

For improved security during file edits that require root access, it’s highly advised to use
sudoedit
(orsudo -e
). This method is considered the standard practice to avoid the security pitfalls associated with directly invoking editors withsudo
. To ensure the use ofnano
withsudoedit
, simply set theVISUAL
environment variable withexport VISUAL=nano
before runningsudoedit
. Alternatively, for a one-off command:VISUAL=nano sudoedit /path/to/file
.Please note that while
sudoedit
is a safer starting point, it’s not the only method available. Alternatives such asdoas
,doasedit
, or leveragingpolkit
withpkexec
can offer even more controlled and secure ways to manage file editing with elevated privileges. However, it’s perfectly acceptable to stick withsudoedit
, as it’s a commonly trusted tool.Be aware that direct usage of
sudo nano
or other editors is strongly discouraged. It bypasses important security mechanisms and can lead to inadvertent system-wide risks.EDIT: changed
VISUAL=nano sudoedit
toVISUAL=nano sudoedit /path/to/file
.On shared systems with untrusted users, you’re right. On your own system when you already have full admin rights,
sudo nano
is fine and doesn’t have any security implications that I’m aware of.
