			How to Edit A Crontab
			---------------------


* The crontab files are in /var/spool/cron/crontabs

* On MDISAS: the crontab files run are by:
	
	adm - system stuff
	covingto - movies
	mdi - data stuff, web pages, idl jobs, screen snaps, opend, archiving
	mdiswms - mirroring 
	root - system stuff and daily backups
	sys - system stuff
	zamkoff - disk usage monitor

* To edit a crontab file the official way

	cd ~mdi/cron
	cp mdi.crontabfile crontab.###### (the date)
	crontab -l > mdi.crontabfile 
		(this copies the current crontab to mdi.crontabfile to
		 make sure it is the most recent)
	diff mdi.crontabfile crontab.###### (the one you just made)
		(see if there is a difference - if so then someone edited
		 the crontab file incorrectly)
	as mdi, edit mdi.crontabfile with your changes and a comment at 
	  the top
 	as mdi, type crontab mdi.crontabfile 
		(this copies the new crontab file to the official crontab)
	send an e-mail to admin saying what you have done
