What the person above me said, OR if you want commands in specific files:

pawn Код:

stock LogCommand(event[])
{
  new File:log = fopen("command_log.txt", io_append);
  fwrite(log, event);
  fwrite(log, "\n");
  fclose(log);
}

Should work by 'LogCommand();', however I did not test the code.

Example usage:

pawn Код:

COMMAND:heal(playerid, params[])
{
  new target;
  if(sscanf(params, "u", target)) return SendClientMessage(playerid, 0x00ff0f00, "Usage: /heal [playerid/name]");
  else if(target == INVALID_PLAYER_ID) return SendClientMessage(playerid, 0x00ff0f00, "Invalid player!");
  SetPlayerHealth(target, 100);
  new gName[MAX_PLAYER_NAME], string[128];
  GetPlayerName(target, gName, MAX_PLAYER_NAME);
  GetPlayerName(playerid, string, MAX_PLAYER_NAME);
  format(string, sizeof string, "[HEAL] %s has healed %s", string, gName); //Important: Formats the string to log
  CommandLog(string); //Log the string
  return 1;
}

Hope that kind of explained it to you.
