Anyone who has used a command line shell on a UNIX system has surely come across a situation with a forgotten sudo. Well, I finally got annoyed enough to look for a solution, an alias to repeat the last command with sudo prepended. And of course, I used please as the alias since I am such a nice person.

For Bash, add the following line/s to ~/.bashrc:

alias pls='sudo $(fc -s)'
alias please='sudo $(fc -s)'

For Zsh, add the following line/s to ~/.zshrc:

alias pls='sudo $(fc -ln -1)'
alias please='sudo $(fc -ln -1)'
