Modes: --reseller [reseller] Update the specified reseller. --all-resellers Update all resellers on the system. --acl-list [acl-list] Update the specified ACL list. --all-acl-lists Update all ACL lists on the system. --help This documentation. =head1 Operations Specify at least one operation. =over =item B<--add-default-privs> Add the default set of privileges, introduced in v68 and later, to the set of resellers and ACLS lists specified. acct-summary basic-system-info basic-whm-functions cors-proxy-get connected-applications cpanel-integration cpanel-api create-user-session digest-auth generate-email-config list-pkgs manage-api-tokens manage-dns-records manage-oidc manage-styles mysql-info ns-config ssl-info track-email =item B<--fix-disallow-shell> Remove the 'disallow-shell' privilege from the set of resellers and specified ACL lists. If the C<disallow-shell> privilege is set, then the script will remove it. If the C<disallow-shell> privilege is not set, then the script adds the C<allow-shell> privilege. =back =head1 Modes Specify at least one mode. =over =item B<--all-resellers> Process all of the resellers on the system. This option overrides B<--reseller>. B<Note>: The script does not process resellers without an associated domain in this mode. =item B<--reseller [reseller-username]> Process the reseller specified. Specify this option multiple times to process mutiple resellers. =item B<--all-acl-lists> Process all ACL lists on the system. This option overrides B<--acl-list>. =item B<--acl-list [acl-list]> Process the ACL list specified.
