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:

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.

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.

:w !sudo tee %

Warning: does not work for neovim

One of the many reasons why I use micro

C-x C-f /sudo::/path/to/file

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.

-- 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

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.
