The scripts in /etc/cron.weekly are all run by the same cron job in /etc/crontab. 47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) I believe that run-parts runs each script in serial, and therefore a long-running weekly script will block. If you don't care when you get the output, and have only one long-running script, you can rename it so that it runs last. Otherwise, you'd need to put the long-running job into its own cron entry. --keith -- kkeller at wombat.san-francisco.ca.us
