From man sudo:
$this->bbcode_second_pass_quote('', '-')s, --shell
Run the shell specified by the SHELL environment variable if it is set or the shell spec‐
ified by the invoking user's password database entry. If a command is specified, it is
passed to the shell for execution via the shell's -c option. If no command is specified,
an interactive shell is executed.
It is not the same as sudo su
