script runs all hunky-dorey in userland.
so time to put it into cron. To cover my bases for inferior cron
environemnt, the first thing the script does is . ~/.bash_profile which in
turn runs ~/.bash_rc which runs /etc/bashrc
So it now looks just like a login env.
maybe...
Except somehow it now spawns _2_ copies of the running process and the race
is on! <insert appropriate swearing here>
Since it's highly sequence dependent data processing and database insertion
and database processing, multiple out of order steps is very, VERY bad.
Solution: make the first line a -f test for a pid file and exit if it
exists. The second line writes the pid file. Shouldn't have to do this...
Still totally stumped on the multiple simultaneous processes.
