Signals also caused problems with fcron on Solaris 2.6 for me so that was another reason to avoid them. Incidentally, this is how cfperl did it, by calling crontab. Sadly I haven't had the time to work on cfperl and cfengine has moved on, but you can find the source code at http://savannah.nongnu.org/projects/cfperl with some examples and a manual. This was cfperl's cfengine-ish language to edit crontabs, from the example configuration file: cron: any:: delete cron cftest delete full cron cftest hourly at 0,10,20,30,40,50 do as cftest /usr/bin/synchronize hourly at * do as cftest /usr/bin/synchronize hourly at 0-59 do as cftest /usr/bin/synchronize daily at 4,5,6 do as cftest /usr/bin/checknetwork daily at 4:30 do as cftest /usr/bin/checknetwork daily at 4,5:30 do as cftest /usr/bin/checknetwork daily at 4,5:30,6:30,7,9:30,4:01,7:01,10:02 do as cftest /usr/bin/checknetwork daily at 1 do as cftest /usr/bin/checknetwork weekly on Monday,Tuesday at 2; on Tuesday,Friday at 8,3; on Thursday at 20,22 do as cftest /usr/bin/checkquotas weekly on Monday,Sunday at 2:40; on Tuesday at 8:10,9:10; on Thursday at 20 do as cftest /usr/bin/checkquotas monthly on 1 at 2:30 do as cftest /usr/bin/checkquotas monthly on 1,2 at 2:10,3:40 do as cftest /usr/bin/checkquotas monthly on 1 at 2; on 4,8 at 4; on 31 at 8 do as cftest /usr/bin/checkquotas yearly in January on 1 at 2; in March on 4,5 at 8:30; in November,December on 28,30 at 20:01,21 do as cftest /usr/bin/checkquotas >From that it would create or edit a crontab with lines as specified. I hope this is of historical interest :) Ted _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
