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

You are entering the 'at' command incorrectly. You need to read the
at(1) documentation ("man 1 at")

But, to make it easier on you, try this...

echo noatun my.mp3 | at 1621

Note that to run a GUI application this way, you /must/ be logged on
to your computer when the command executes. If you are not logged on,
then the command will not be able to run on your desktop and you will
get an email from at complaining
Error: Can't open display:

If you /want/ to use the at(1) command, use it to run a non-GUI
application (like aplay for wav files or mpg123 for mp3 files)

Minor correction - try
echo DISPLAY=$DISPLAY noatun my.mp3 | at 1621

You need the DISPLAY environment variable to allow noatun to display
on your logged on X session. Of course, if you log off before noatun
runs at 1621, you won't own the display that the DISPLAY variable
points to, and noatun will crash with that "Error: Can't open display"
message

Yes, you were right. However, if I type noatun my.mp3, I get 'noatun'
the file playing, but when using your suggestion I get noatune, but it
does not play the the mp3 file (!?).
What am I doing wrong?
Right now is 00 :30 here, so I will pack it up and try again tomorrow.
Thanks!!
