An alias to re-run last command with sudo. Similar to "sudo !!"

alias please='sudo $(fc -ln -1)'
I didn't come up with this myself, but I always add this to my .bash_aliases file. It's essentially the same idea as running "sudo !!" except it's much easier to type. (You can't just alias "sudo !!", it doesn't really work for reasons I don't understand.) "fc" is a shell built-in for editing and re-running previous commands. The -l flag tells it to display the line rather than edit it, and the -n command tells it to omit the line number. -1 tells it to print the previous line. For more detail: help fc

What Others Think

You should have a look at this : https://github.com/nvbn/thefuck ! Not only it enabled the "forgotten sudo" stuff, but also helps you when you misspell any other command.

Nice solution. Seems to be cross platform, too (well, Linux and OpenBSD anyway); just need to replace 'sudo' with 'doas' for OpenBSD (or symlink 'sudo' to 'doas').
