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

  • What is the difference between su - , sudo bash and sudo sh?
    su -: This will change your user identifier and inherit the environment variables as if you had logged in with that user Normally you would use the format su - <userid> to login as the user If you drop the "userid" it assumes you are trying to login as root - which you can't (unless you change the root password) sudo bash sudo sh: Anything after the sudo is a program to run - so in these

    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
  • sudo su - vs sudo -i vs sudo bin bash - when does it matter . . .
    sudo su - This time it is a login shell, so etc profile, profile and bashrc are executed and you will find yourself in root's home directory with root's environment sudo -i It is nearly the same as sudo su - The -i (simulate initial login) option runs the shell specified by the password database entry of the target user as a login shell
  • 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)
