Stupid crontab trick of the decade (I was going to write "of the day"
but I don't want to do a daily crontab trick):

Save a copy of your crontab in your home directory.  I call mine
".crontab".  Change its mode to 700.  Put this on the first line of
the file:

#!/usr/bin/crontab

Hooray!  Now you can simply edit this file and then *run it* to update
your crontab.

Want to make your crontab automatically update itself after you edit
it!?!?!??  Add this job to it and then run it manually (for the last
time!):

* * * * * $HOME/.crontab

The interpretter trick also works for screen and apache configuration
files.  Really it could potentially work for any program that can take
the name of its configuration file on the command line and uses # as
the comment marker.

Ok bye.
