When you realized you forgot sudo

    
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  Mail

Considering 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 the fc -ln -1 command in a subshell instead. Note the response that says eval shouldn’t be used (not sure why)
- no because it takes the previous command and adds sudo to it right?

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
Lazier way:
:w !sudo tee %
- Yeah learning about tee from 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.

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
Yeah, in emacs you use tramp to open the file with /sudo::
(n)vim + suda.vim.
It's a simple trick in Vim:

For the lazy: :w !sudo tee > /dev/null %
micro ftw, no need to even memorize a command, it'll just ask if you want to use sudo
kate does this in KDE, but it's not cli.

    
:w !sudo tee %

Warning: does not work for neovim

- 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.

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

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.

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.

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.

lua

    
-- 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:

 vimscript

    
" Disable Suda in diff views
if ! &diff
    let g:suda_smart_edit = 1
endif
