It 28168404Spjdis functionally based on the SysV cron, which means that each user can have 29168404Spjdtheir own crontab file (all crontab files are stored in a read-protected 30219089Spjddirectory, usually /var/cron/tabs). No direct support is provided for 31219089Spjd'at'; you can continue to run 'atrun' from the crontab as you have been 32168404Spjddoing. If you don't have atrun (i.e., System V) you are in trouble. 33168404Spjd 34168404SpjdA messages is logged each time a command is executed; also, the files 35168404Spjd"allow" and "deny" in /var/cron can be used to control access to the 36168404Spjd"crontab" command (which installs crontabs). It hasn't been tested on 37168404SpjdSysV, although some effort has gone into making the port an easy one. 38168404Spjd 39168404SpjdThis is more or less the copyright that USENET contributed software usually 40168404Spjdhas. Since ATT couldn't use this version if they had to freely distribute 41168404Spjdsource, and since I'd love to see them use it, I'll offer some rediculously 42219089Spjdlow license fee just to have them take it. In the unlikely event that they 43219089Spjddo this, I will continue to support and distribute the pseudo-PD version, so 44219089Spjdplease, don't flame me for wanting my work to see a wider distribution. 45219089Spjd 46219089SpjdTo use this: Sorry, folks, there is no cutesy 'Configure' script. You'll 47219089Spjdhave to go edit a couple of files... So, here's the checklist: 48219089Spjd 49219089Spjd Read all the FEATURES, INSTALL, and CONVERSION files 50219089Spjd Edit config.h 51219089Spjd Edit Makefile 52219089Spjd (both of these files have instructions inside; note that 53219089Spjd some things in config.h are definable in Makefile and are 54219089Spjd therefore surrounded by #ifndef...#endif) 55219089Spjd 'make' 56219089Spjd 'su' and 'make install' 57219089Spjd (you may have to install the man pages by hand) 58219089Spjd kill your existing cron process 59219089Spjd (actually you can run your existing cron if you want, but why?) 60219089Spjd build new crontabs using /usr/lib/{crontab,crontab.local} 61219089Spjd (either put them all in "root"'s crontab, or divide it up 62219089Spjd and rip out all the 'su' commands, collapse the lengthy 63219089Spjd lists into ranges with steps -- basically, this step is 64219089Spjd as much work as you want to make it) 65219089Spjd start up the new cron 66219089Spjd (must be done as root) 67219089Spjd watch it. test it with 'crontab -r' and watch the daemon track your 68219089Spjd changes. 69219089Spjd if you like it, change your /etc/{rc,rc.local} to use it instead of 70219089Spjd the old one. 71219089Spjd 72219089Spjd$FreeBSD$ 73219089Spjd
