fuck() { sudo $(fc -ln -1) }This function takes the last command and puts sudo in front of it. Actually used it in a zoom call at work without thinking and it took a second to realize why everyone was laughing. Not my invention–came across it years ago on stackoverflow or someplace and thought it was funny/useful.
kmirl@tux:~$ ls /root ls: cannot open directory '/root': Permission denied kmirl@tux:~$ fuck [sudo] password for kmirl: bin debs docs MailConsidering the function name, here’s an obligatory thefuck plug
Isn’t this the same effect as just running ‘sudo !!’ ?
According to this super user question, someone said that
!!won’t work in a function, so you must use thefc -ln -1command in a subshell instead. Note the response that saysevalshouldn’t be used (not sure why)Yeah but instead of a function you just make it an alias.
Oh good point, I didn’t think about that
Eval shouldn’t be used on userinput. Meaning that if smb other than you may use this to change the system he could put malicious code in the eval part.
Probably doesn’t matter on shell level
no because it takes the previous command and adds sudo to it right?
!!is a shortcut for whatever the last command wasis it not?
alias fuck='sudo $(fc -ln -1)'
Lazy vim way I do it:
ggVG"wY:q!followed bysudo !!thenVG"wp:xGrab entire file and stuff it in register W
Exit file
Reopen sudo
Select all and replace with register W them write
Now I understand how the Adeptus Mechanicus feel when they perform a ritual power-on.
It’s funny how years of use make that so intuitive but spelled out it’s a garbled mess
Lazier way:
:w !sudo tee %Yeah learning about
teefrom this thread honestly.It’s been interesting realizing I had such a useful tool at my disposal but never knew
Is there an editor that can request root privileges without restarting it? That would be quite useful.
In vim, in normal mode you can do:
:w !sudo tee %Apparently that doesn’t work in NeoVim, so recently I installed the suda plugin.
Personally, I just doas nvim and then the file name that needs root access, but it’s a handy plugin in case I forget.
??? I used this in neovim twice today
:w !sudo tee %then reload when it asks.
i use micro
Sure, you can do this in emacs: https://fuco1.github.io/2017-04-20-Save-write-protected-files-with-sudo-automatically.html
katedoes this in KDE, but it’s not cli.It’s a simple trick in Vim:

For the lazy:
:w !sudo tee > /dev/null %Yeah, in emacs you use
trampto open the file with/sudo::micro ftw, no need to even memorize a command, it’ll just ask if you want to use sudo
(n)vim + suda.vim.
Kwrite/Kate asks you for password. Seriously, why can’t they all just use pkexec or some abstraction of it?
Sadly, i currently borked all Qt apps on my Gtk setup.
So does Micro. Nano… Nano does not.
Eh, on console i can just do
ssu nano <file>. Graphical editors are in question.
:w !sudo tee %Warning: does not work for neovim
Neovim, the one true vim, why hast thou forsaken me.
Iirc the specific reason behind this is
- sudo by default requires a tty to run
- vim’s bang spawns a tty to execute commands
- nvim’s bang executes the command directly, then pipes the output to nvim
As a result, sudo (without args) can’t work in nvim as it doesn’t have a tty to prompt the user for passwords. Nvim also used to do what vim did, but they found out spawning the tty was causing other issues (still present in vim) so they changed it.
There must be more to this. I just launched a terminal and created a file to test with nvim on arch and it works perfectly fine.
Take a file, sudo chown root:root filename, sudo chmod 700 filename, edit with nvim and save with :w !sudo tee % then reload. Works fine.
I’m on arch with suckless st.
Edit:
Made a demo vid - https://youtu.be/YKZuAvoSW5g
I didn’t do any editing since it’s just to prove a point, but I think it does fine.
One of the many reasons why I use micro

I love Emacs. Thanks for teaching me someyhing today
I am here for one reason and one reason alone: source anime is Watamote, episode 12 @18:36
Tomoko tries to approach a girl, but the wind confuses her and she runs away in embarrassment, even though the girl was really friendly and would have liked to talk to her.
In the meme, this scene is used to parallel the feeling of an external system blocking an operation that both participants would agree to.
A similar feeling could be memed with the “myth of consensual sex” format.
sudoeditis more secure btw. Many editors are not built to be ran as root, and this copies the file to a temo directory, edits it without root, and then overwrites the original file on save with root.Use suda.vim for automatically dealing with such cases. Works with
neovimas well.I’ll also recommend adding the following to your
init.luaor some config file becausesudadoesn’t play nicely withnvim -dorvimdiff.-- Disable Suda in diff views if not vim.api.nvim_win_get_option(0, 'diff') then vim.g.suda_smart_edit = 1 endThe
vimscriptversion of the same would be:" Disable Suda in diff views if ! &diff let g:suda_smart_edit = 1 endifdeleted by creator
