   I don't like keeping similar information in multiple places (especially
   in different formats) because you have to access it in different ways.
   If I change my own crontab file using "crontab -e", I want to do root's
   the same way; it's just one less exception for me to remember.

I've learned not to touch /etc/crontab at all. Saves some time during
upgrades/mergemaster.

I don't think this is sound advise. Leaving /etc/crontab (the system crontab) 
to do
the system maintenance jobs it is supposed to do and putting additional scripts 
and 
jobs in user tabs is normal practice and won't cause any problems.

   They're in /var/cron/tabs.  If you're using individual crontab files,
   be sure to rename /etc/crontab or you might have duplicated cronjobs
   running simultaneously.

   I use the file header beneath my signature for crontab files, so I
   don't forget what field goes where.  It's also handy to define an
   environment variable in case a program should behave differently when
   run under cron.

location of user crontab files?

2009-08-11 Thread Identry
Where are user crontab files stored in the file system?

I used to create user crontab files and then load them with 'crontab
name-of-cronfile', but then I got clever and discovered 'crontab -e'.
The problem is, that doesn't give me the 'backup' of having a text
crontab file.

The system must store the info somewhere so it's available after a
reboot, but where? I want to make sure this info is backed up.

Thanks: John
