[ubuntu-uk] "at" command examples / usage

[Kirrus]

Hi,

Can anyone give me any more useful examples of using / help with using at?
I'm trying to run this command, but its silently failing, and the man page really isn't that helpful for a newbie...

user at jon:~# at scp jt.tar.gz 10.2.0.58:/opt/ltsp/ 1800
syntax error. Last token seen: s

user at jon:~# at "scp jt.tar.gz 10.2.0.58:/opt/ltsp/" 1800

user at jon:~# at "scp jt.tar.gz 10.2.0.58:/opt/ltsp/" 6pm
syntax error. Last token seen: s

user at jon:~# at 6pm "scp jt.tar.gz 10.2.0.58:/opt/ltsp/"

Any ideas/suggestions?
