su gimtadieniuvyruibaltoji peleda represents a topic that has garnered significant attention and interest. What are the differences between "su", "sudo -s", "sudo -i", "sudo su"?. sudo su Asks your password, becomes root momentarily to run su as root. So in this case you are running su using sudo and you don't have to know root's actual password.
The results are same as su and su -. su - user Vs sudo su - user - Unix & Linux Stack Exchange. Additionally, 8 sudo su - will elevate any user (sudoer) with root privilege. su - anotheruser will switch to user environment of the target user, with target user privileges What does sudo su - username mean? What is the difference between 'su -' and 'su root'?
8 su - switches to the superuser and sets up the environment so that it looks like they logged in directly. It's important to note that, su root switches to the user named root and doesn't simulate directly logging in. If the superuser is named root, then su and su root are equivalent (and don't simulate directly logging in), as are su - and su - root (which do). Why do we use su - and not just su?
- Unix & Linux Stack Exchange. su - logs you in completely as root, whereas su makes it so you are pretending to be root. The most obvious example of this is that ~ is root's home directory if you use su -, but your own home directory if you use su. This perspective suggests that, su vs sudo -s vs sudo -i vs sudo bash - Unix & Linux Stack Exchange.
su is equivalent to sudo -i and simulates a login into the root account. Your working directory will be /root, and it will read root's .profile etc. The prompt will change from $ to #, indicating you have root access. sudo -s launches a shell as root, but doesn't change your working directory. It's important to note that, sudo bash where bash is command to run with sudo.

Is there a single line command to do `su`? Here's why: If you write a password in a command like su <username> -p <password>, it would be stored in plain text in your bash history. This is certainly a huge security issue. If you need to run commands with su (or sudo) in an automated way, write a shellscript containig the commands without su or sudo and run su <username> script.sh
From su 's man page: For backward compatibility, su defaults to not change the current directory and to only set the environment variables HOME and SHELL (plus USER and LOGNAME if the target user is not root). It is recommended to always use the --login option (instead of its shortcut -) to avoid side effects caused by mixing environments.
