Sketchy notes on S3 segment list auto-generation
Peter Shawhan
December 1, 2003

I have set up a cron job at each site to generate an up-to-date cumulative segment list for the S3 run every 5 minutes.  The lists are written to files called S3H1v00_segs.txt, etc., and have four values per line: segment number, start time, stop time, and duration.

The cron job simply executes the 'generate_S3_seglists' script.  At
LHO, the cron job runs on the h1injection machine; at LLO, it runs on
the control14 machine.  In both cases, it runs under the 'ops'
account.

For example, at LHO, the crontab line (on h1injection, user 'ops') is:
