I am not sure if this is the right place to post question about UNIX
commands, so, at risk of being fertilized I will go on with my
quesion.
I want to noatun to start playing an mp3 file exacly at 4:21 pm.
'noatun my.mp3' plays the my mp3 file, so.... 'at noatun my.mp3 4:21pm
' should play the file, but 'at' complains, what am I doing wrong?

As an excuse for the stupidity of my question, I must say, this is the
first time I am using the 'at' command and that I am not an expert
UNIX programmer.

Thanks folks, and apologize if I am in the wrong newsgroup
