did one of those entirely in bash. start with a script much like
those that live in /etc/init.d, add an entry for cron, when it forks
itself redirect all input and output to /dev/null, so when you invoke
it from a prompt it won't get hung up in shell job control. you can
scatter the code into multiple script files if you like but the one i
did was all in one file. you'll of course need to handle simultaneous
invocations, via cron or otherwise. the strategy i used was to have
the old one voluntarily die when a new one gets launched.
> Alternatively you can put an entry in /etc/inittab
recent versions of ubuntu omit /etc/inittab.
