Hi,
When I run the following it works:
sudo ls /root/
I wanted to see root user history. So I ran
sudo history
It said:
Password: sudo: history: command not found
How come it is not working? How do I tell sudo to run the history command on Linux system?
The history is a shell builtin command. We can see it as follows:
type -a history
command -V history
The trick is to run bash shell with sudo and then call history. One way to do this:
sudo bash -i <<<history
Another option:
sudo cat ~/.bash_history
sudo cat ~/.bash_history | grep 'something'
But I agree @monk’s solution is pretty good.
Huh, didn’t know you could use a Here String like that. I always used it to redirect either a var or the stdout of a subprocess.
