Comment:
a. May I conclude that you can't be sure "nice" is on your systemin that case the line should be deleted, and all of its's argument as wellHow should the command look like in that case?b. Or that the line is wrong?Just changing it to /bin/nice would be enoughc. Or that the line is dependent of your system?And, if the last is true:How should anyone be able to check that?Rein
