This is a simple plugin that checks if the command typed in the chat by the player exists or not.

Will only work for commands created with RegAdminCmd(), RegConsoleCmd() and RegServerCmd(), not created with AddCommandListener(*, "say") and AddCommandListener(*, "say_team") hooks.

@leandro442, 1st post doesn't describe the plugin's appointment in full !

...
	AddCommandListener(block, "status");
	AddCommandListener(block, "ping");
	AddCommandListener(block, "stats");
}

public Action block(int client, const char[] command, int args)
{
	return Plugin_Handled;
}

This should be mentioned! Because it may cause conflicting with other plugins.
"status" method sometimes used for OS detection.

There is no hardcoded /! symbols in SM. It is controlled by configs/core.cfg => "PublicChatTrigger", "SilentChatTrigger" values.

#include <cstrike> is not necessary.

Plugin returns incorrect info when the following command has entered in chat: !sm_admin

Alternate plugin: [ANY] !COMMAND eater
