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

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 the fc -ln -1 command in a subshell instead. Note the response that says eval shouldn’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
no because it takes the previous command and adds sudo to it right?
!! is a shortcut for whatever the last command was ~~is it not?~~
alias fuck='sudo $(fc -ln -1)'
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
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
Is there an editor that can request root privileges without restarting it? That would be quite useful.
Yeah, in emacs you use tramp to open the file with /sudo::
kate does this in KDE, but it's not cli.
It's a simple trick in Vim:

For the lazy: :w !sudo tee > /dev/null %
i use micro
micro ftw, no need to even memorize a command, it'll just ask if you want to use sudo
Sure, you can do this in emacs: https://fuco1.github.io/2017-04-20-Save-write-protected-files-with-sudo-automatically.html
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.
: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
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.
One of the many reasons why I use micro
C-x C-f /sudo::/path/to/file
I love Emacs. Thanks for teaching me someyhing today
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:
if ! &diff
let g:suda_smart_edit = 1
endif
