What is the difference between sudo s and sudo I?
Sudo -s is a “non-login” style shell. This means that unlike a command like sudo -i or sudo su , the system will not read any environmental files. 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. Your home will not be the root home, etc.
What is sudo s command?
The sudo command allows you to run programs with the security privileges of another user (by default, as the superuser). It prompts you for your personal password and confirms your request to execute a command by checking a file, called sudoers , which the system administrator configures.
What is the difference between sudo su and sudo bash?
sudo su lauches su directly with super user privileges, while sudo bash lauches the shell first and then executes the command with bash -c . The main difference would be that your . bashrc script will be run before executing the su – root command. The outcome depends on that.
What happens when you do sudo su?
The su command switches to the super user – or root user – when you execute it with no additional options. You’ll have to enter the root account’s password. This isn’t all the su command does, though – you can use it to switch to any user account.
What are some of the basic Sudo commands?
Basic commands to remember: root@server :~# cd / this will open the root directory. root@server :~# cd .. open one level up directory. root@server :~# cd – will open the home directory
