    Name        : sudo
    Product     : Fedora 33
    Version     : 1.9.5p1
    Release     : 1.fc33
    URL         : https://www.sudo.ws
    Summary     : Allows restricted root access for specified users
    Description :
    Sudo (superuser do) allows a system administrator to give certain
    users (or groups of users) the ability to run some (or all) commands
    as root while logging all commands and arguments. Sudo operates on a
    per-command basis.  It is not a replacement for the shell.  Features
    include: the ability to restrict what commands a user may run on a
    per-host basis, copious logging of each command (providing a clear
    audit trail of who did what), a configurable timeout of the sudo
    command, and the ability to use the same configuration file (sudoers)
    on many different machines.
