When sudo su vs sudo -i [duplicate]

  • 772

I am reading some tutorials about Linux configurations:

  • To accomplish many of the configurations is important and mandatory be the root.

Well I did realize that in many places are used sudo su and sudo -i, even when both accomplish the the same goal, I have the doubt about:

  • when is mandatory use one approach over the other?

I am doing this question because for some reason exists these two approaches

command-line sudo su

    As pointed by the user @user535733 in the comments section, both commands will take you to different working directory.

    sudo su will execute commands as root in your present working directory but sudo -i will take you to your root's home directory (by default to /root)

    Another difference is if you are using anything other than bash as your shell sudo -i and sudo su will take you to the shell configured for the root user (bash is default in Ubuntu) while sudo -s uses the shell you configured for your user(e.g, zsh)
