What to do when you write a long command, and realize that you forgot to write sudo.
Q. I keep forgetting about writing
sudo in front of commands since I switched to Ubuntu from other Linux distribution, is there an easy way to repeat the command with sudo in front of it?
A. You only need to creat an alias, that will call the last command with the command
sudo in front of it, and you don't need to type the whole command again.
Do something like this:
alias sorry='sudo $(history -p \!\!)'
Now, next time you run:
service postfix restart
And the server says:
-bash: service: command not found
And it will ask for your password and complete the task
