The famous Vim sudo-write trick: You open a file, edit it, and save it only to get the E45 error message. You now realize that only root can edit the file. What do you? Start over? No, instead try this:
:w !sudo tee "%"
Learnt it from vim.fandom.com/wiki/Su-write?… back in 2005.
#vim
:w !sudo tee "%"

#vim
How does :w !sudo tee "%" work?
:w !{cmd} - Executes {cmd} with all lines in buffer as standard input.
% - Expands to current filename. Quotes around it keep it as a single argument even if the filename contains whitespace.
tee {file} - Copies stdin to stdout and {file}.
#vim
:w !{cmd} - Executes {cmd} with all lines in buffer as standard input.
