- 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 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 -
- What is the difference between su - and su root? [duplicate]
8 su - switches to the superuser and sets up the environment so that it looks like they logged in directly 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)
- su - user Vs sudo su - user - Unix Linux Stack Exchange
Secondly: sudo -i and su - do the same thing (su - is equivalent to su --login), using different authorization mechanism: su verifies the password for the root account, while sudo verifies the password for your current user account and also verifies that your current user account is allowed to run administrative operations according to the etc sudoers policy This is the reason sudo is
- Why do we use su - and not just su? - Unix Linux Stack Exchange

- su vs sudo -s vs sudo -i vs sudo bash - Unix Linux Stack Exchange

- Whats the difference between `su -` and `su --login`? - linux
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 -, -l, --login Start the shell as a login shell

- Is there a single line command to do `su`? - Ask Ubuntu
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
