to avoid confusion, I usually have special scripts set up to do the actual
work of the cron job, and I just have cron run the script.
So have a script which does what you want, that doesn't rely on ~ expansion
or environment variables. Then run that script from cron, instead of the
specified command line.
Is there any real need to launch setiathome two minutes past the five
minute mark? If you were launching a very heavy but short running program,
I could understand staggering start times, but for setiathome which is a
long running program, you may as well specify the time as "*/5 * * * *" to
save space :)
