Executor helps executing commands ingame on the server, the Minecraft-server runs on(with /run <yourpassword(default is 1234test)> <command>).
You can define a backup shell script and backup with /backup <yourpassword(default is 1234test)>.
Config can be found in /plugins/Executor/Config.yml.
I don't take any responsibility for the damage and the security-issues this plugin causes on your server.
This plugin runs fine on my server g.ossa.de.
Attention! This plugin requires Java 8 on the Server.
Only one player can use this plugin at one Time.
Executor.backup #for /backup <password> <command>
Executor.run #for /run <password> <command>
If you like the Plugin, I would be very happy about a donation!
