StartupCommands
StartupCommands lets a server owner set console commands that run once each time the server starts, with three in-game commands to manage the list.
What it does
Command lists are kept on the server, and each entry is executed when the server boots. Server owners add entries with the addstartupcommand command and remove them with removestartupcommand, and the list can be cleared as a whole. The mod runs only on the server, so players join without installing it and clients need nothing extra.
The commands in the list execute one second apart, which keeps the order fixed: each command finishes before the next one starts. The mod is published for Fabric under the Apache License 2.0 with source code and an issue tracker, and files cover 1.20.1, 1.20.4, 1.20.5, 1.20.6 and 1.21.8.
Key features
Startup command list
Any number of console commands can be stored and run automatically when the server starts.
Three management commands
The startupcommands set, add and remove subcommands edit the list from the server console or in-game.
Sequential execution
Entries run one second apart, so each one completes before the next takes place.
