No. Without the space between "0" and ">", you are doing I/O redirection, which is something completely different. So it can't be a valid fix. It is expected that this echo command can fail, if the driver doesn't support disabling fan speed control. However the failure should be silent. I wonder why the error shows in Torsten's case. Torsten, what version of bash are you using? Is the pwmconfig script somehow modified by your distribution? Or did you modify it by yourself? For now, you can just ignore the error messages. -- Jean Delvare
