How does Sudo -s work in Linux?

This command works as if the user is running sudo /bin/bash. Sudo -s is a “non-login” style shell.

This means that when a user tells the shell to run sudo -s, it gains root but will not change the user or the user environment.

How do I switch users in Sudo?

This command is essentially the same as just running su in the shell. Instead of telling the system to “switch users” directly, you’re telling it to run the “su” command as root. When sudo su is run, “.profile,” “.bashrc” and “/etc/profile” will be started, much like running su (or su root).

Is it possible to trace what a user did through Sudo?

Although commands run through ‘sudo’ are executed as the target user (which is ‘root’ by default), they are tagged with the sudoer’s user-name. But in case of ‘su’, it’s not possible to directly trace what a user did after they su’d to the root account.
