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 thefc -ln -1
command in a subshell instead. Note the response that sayseval
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
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 wasis it not?
alias fuck='sudo $(fc -ln -1)'
Lazy vim way I do it:
ggVG"wY:q!
followed bysudo !!
thenVG"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
One of the many reasons why I use micro
Is there an editor that can request root privileges without restarting it? That would be quite useful.
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.Yeah, in emacs you use
tramp
to open the file with/sudo::
i use micro
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.
It’s a simple trick in Vim:

For the lazy:
:w !sudo tee > /dev/null %
Sure, you can do this in emacs: https://fuco1.github.io/2017-04-20-Save-write-protected-files-with-sudo-automatically.html
: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.
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 becausesuda
doesn’t play nicely withnvim -d
orvimdiff
.-- 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

I love Emacs. Thanks for teaching me someyhing today
