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.

According to this super user question, someone said that !! won’t work in a function, so you must use the fc -ln -1 command in a subshell instead. Note the response that says eval shouldn’t be used (not sure why)
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
!! is a shortcut for whatever the last command was is it not?
Lazy vim way I do it:
ggVG"wY:q! followed by sudo !! then VG"wp:x
Grab entire file and stuff it in register W
Exit file
Reopen sudo
Select all and replace with register W them write
Is there an editor that can request root privileges without restarting it? That would be quite useful.
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.
Sure, you can do this in emacs: https://fuco1.github.io/2017-04-20-Save-write-protected-files-with-sudo-automatically.html
It's a simple trick in Vim:

For the lazy: :w !sudo tee > /dev/null %
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.
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.

I didn't do any editing since it's just to prove a point, but I think it does fine.

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.
sudoedit is 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 neovim as well.
I'll also recommend adding the following to your init.lua or some config file because suda doesn't play nicely with nvim -d or vimdiff.
-- Disable Suda in diff views
if not vim.api.nvim_win_get_option(0, 'diff') then
vim.g.suda_smart_edit = 1
end
The vimscript version of the same would be:
" Disable Suda in diff views
if ! &diff
let g:suda_smart_edit = 1
endif
I've used bash as my shell for so long my fingers type sudo !! without me having a conscious thought about it.
