Sudo-komennon avulla voit ajaa ohjelmia toisen käyttäjän suojausoikeuksilla (oletusarvoisesti pääkäyttäjänä). Se pyytää sinua antamaan henkilökohtaisen salasanasi ja vahvistaa pyyntösi suorittaa komennon tarkistamalla sudoers-nimisen tiedoston, jonka järjestelmänvalvoja määrittää.

Yleisin komento jolla päästään pääkäyttäjäksi ja samalla root kotikansioon on sudo -i
