Bulk Editing
LuckPerms provides a command to help perform bulk permission modifications with ease. This command should be used with care, as it can easily corrupt or break your setup if used in the wrong way.
It may be wise to take a backup of your permission data before using the command, either by making a copy of your database / files, or by using the export command.
The commands design is basically stripped back SQL syntax. This means the data passed into the command can be converted directly to an SQL query, or used to modify data in YAML or JSON storage files. Those who have experience with SQL may find it easier to write queries directly into their database server instead of using this command.
These commands are only available from the console. This is because they have the potential to cause a great deal of damage to your servers data. You are asked to type a confirmation code before the action is processed, in order to prevent users from "sudoing" the console and gaining access to these commands.
The command usage is as follows...
/lp bulkupdate <data type> <action> [action field] [action value] [constraint...]🔗
A bit daunting at first, I know. To break it down...
| Argument | Description |
|---|---|
data type | the type of data being changed. (can be "all", "users" or "groups") |
action | the action to perform on the data. (can be "update" or "delete") |
action field | the field to act upon. only required for update actions. (can be "permission", "server" or "world") |
action value | the value to replace with. only required for update actions |
constraint | the constraints required for the update |
The data type is the simple bit. It simply tells LuckPerms what data should be affected by the update. Either just users, just groups, or users and groups.
The action is what will be done to the data. It can either be "update" or "delete". Delete simply means that any records which match the constraints will be deleted. Update will replace any values that match with another value.
The action field and action value arguments are optional because they only apply to the "update" action. The field is what will be updated, and the value is the replacement value for the field.
The constraints argument relates to the limitations of the update. Only the permissions (or entries) which match the constraints will be affected.
Constraints 🔗
Constraints are split into 3 parts. The field, the comparison and the value.
The available fields are permission, server and world. Permission is just the permission node being stored in the file (remember that everything, even group memberships and prefixes are stored as permissions "under the hood"). The server and world fields relate to the server/world where the permission will apply. They are set to "global" if the permission doesn't have a value for either of them.
The value part of the constraint is just the expected value of the field, with respect to the comparison being used.
There are 4 different comparisons available.
| Comparison Symbol | Comparison Name | Description |
|---|---|---|
== | Equal to | If the two values are the same. (ignores case) |
!= | Not equal to | If the two values are not the same. (ignores case) |
~~ | Similar to | If the two values are "similar". Uses SQL's LIKE syntax. |
!~ | Not similar to | If the two values are not "similar". Uses SQL's LIKE syntax. |
More information about the syntax used by "similar" can be found here and here.
The basic idea is that:
%- The percent sign represents zero, one, or multiple characters_- The underscore represents a single character
Some examples 🔗
server ~~ hub_will match server values "hub1", "hub2", "hub3" etcpermission !~ group.%will match any permission which isn't a groupworld == netherwill match world values exactly equal to "nether"
When constraints are defined in commands, the entire constraint must be wrapped with " " quotes.
Command Examples 🔗
/lp bulkupdate all update permission group.mod "permission == group.moderator"🔗
Will update all entries, and replace any occurrence of the "group.moderator" permission with "group.mod". (effectively renaming the group)
/lp bulkupdate users delete "server ~~ hub%" "world == nether"🔗
Will delete any permission assigned to a user where the server starts with "hub" and the world is equal to "nether".
/lp bulkupdate all delete "permission == essentials.fly"🔗
Will delete any permission entry where the permission is equal to "essentials.fly"
/lp bulkupdate all delete "permission == group.vip"🔗
Will delete all memberships of the VIP group.
/lp bulkupdate all update server global "server == factions"🔗
Will change any server entries from "factions" to "global"
/lp bulkupdate all update permission essentials.ban "permission == essentials.mute" "server == survival"🔗
Will change any permission entries for "essentials.mute" to "essentials.ban" set on the "survival" server
