TIMEKEEPING-PERSONAL CRON DAEMON
From: Mike Andrew Oct 2001
A personal cron daemon is available to every user. It acts identically to the superuser, is subject to the same rules and syntax, but naturally, can only execute user-permissioned jobs.
The all important file is $HOME/crontab
simply place anything you would as per an /etc/crontab, omitting the 'user' field.
a mere-mortal's crontab looks as follows
Step 1) create a crontab file
*/1 * * * * ./testit # run something every minute
step2) create testit
echo "hello" >a_file
step 3) change permissions
chmod 700 testit
step 4) fire cron
All other information is in crontab for superman
