In case you are running Linux on a machine that you normally use alone, say on a laptop, entering a password each time you invoke\u00a0sudo<\/strong>\u00a0can become so boring in the long run. Therefore, in this guide, we will describe\u00a0how to configure sudo command<\/a>\u00a0to run without entering a password.<\/p>\n

This setting is done in the\u00a0\/etc\/sudoers<\/strong>\u00a0file, which drives sudoers to use default security policy plugin for the\u00a0sudo command<\/a>; under the user privilege specification section.<\/p>\n

Important<\/strong>: In the\u00a0sudeors<\/strong>\u00a0file, the authenticate parameter which is turned on by default is used for authentication purposes. If it is set, users must authenticate themselves via a password (or other means of authentication) before they run commands with\u00a0sudo<\/strong>.<\/p>\n

However, this default value may be overridden using the\u00a0NOPASSWD<\/strong>\u00a0(require no password when user invokes\u00a0sudo<\/strong>\u00a0command) tag.<\/p>\n

The syntax to configure user privileges is as follows:<\/p>\n

user_list host_list=effective_user_list tag_list command_list\r\n<\/pre>\n
Where:<\/p>\n
    \n
  1. user_list<\/code>\u00a0\u2013 list of users or a user alias that has already been set.<\/li>\n
  2. host_list<\/code>\u00a0\u2013 list of hosts or a host alias on which users can run sudo.<\/li>\n
  3. effective_user_list<\/code>\u00a0\u2013 list of users they must be running as or a run as alias.<\/li>\n
  4. tag_list<\/code>\u00a0\u2013 list of tags such as NOPASSWD.<\/li>\n
  5. command_list<\/code>\u00a0\u2013 list of commands or a command alias to be run by user(s) using sudo.<\/li>\n<\/ol>\n
    To allow a user (aaronkilik<\/code>\u00a0in the example below) to run all commands using\u00a0sudo<\/strong>\u00a0without a password, open the\u00a0sudoers<\/strong>\u00a0file:<\/p>\n
    $ sudo visudo\r\n<\/pre>\n
    And add the following line:<\/p>\n
    aaronkilik ALL=(ALL) NOPASSWD: ALL\r\n<\/pre>\n
    For the case of a group, use the\u00a0%<\/code>\u00a0character before the group name as follows; this means that all member of the\u00a0sys<\/code>\u00a0group will run all commands using sudo without a password.<\/p>\n
    %sys ALL=(ALL) NOPASSWD: ALL\r\n<\/pre>\n
    To permit a user to run a given command (\/bin\/kill<\/code>) using sudo without a password, add the following line:<\/p>\n
    aaronkilik ALL=(ALL) NOPASSWD: \/bin\/kill\r\n<\/pre>\n
    The line below will enable member of the\u00a0sys<\/code>\u00a0group to run the commands:\u00a0\/bin\/kill<\/strong>,\u00a0\/bin\/rm<\/strong>\u00a0using\u00a0sudo<\/strong>without a password:<\/p>\n
    %sys ALL=(ALL) NOPASSWD: \/bin\/kill, \/bin\/rm\r\n<\/pre>\n
    \n
    \"Run<\/a><\/p>\n
