I'm running a Bukkit server, on which I am trying to use Command Blocks to run commands. In one Command Block, I have tried to use save-all, but when activated, nothing happens
The command sudo works, as i tried /sudo @a gc
But the sudo command doesn't work with save-all either.
The syntax for the sudo command is /<command> <player> <command [args]> and its description is Make another user perform a command. With the command /sudo @a gc you force every player to execute /gc. Means everyone see the server usage information.
If you typed /sudo @a save-all in the commandblock, be happy that it dosen't work because that could be ending in a server crash. (Everybody on the server is forced to execute the command /save-all, what needs much hardware usage)
What I think that you missleading it with the sudo command from linux where the command is executed as root.
The problem why you can not execute the command /save-all in a commandblock is because it is disabled from the server itself for security reasons.
In the Minecraft Wiki you find that information:
These commands are likely disabled due to limited use in command blocks and the potential for severe, unintended consequences on servers.
That counts for the commands:
ban, ban-ip, deop, kick, op, pardon, pardon-ip, save-all, save-off, save-on, stop, whitelist add/remove/on/off/reload, debug, publish
If you really need that command, the only possibility is to use a command of a other plugin and not the original command /save-all.
But make sure that it is executed only once! Keep in mind that griefer could use it to crash the server by expensive hardware usage if they spam the button!
