Solaris

Hi all -

I've searched the forums and seen a few questions related, but nothing which explicitly answers what I'm looking for.

I need to know if there's ANY way to get the modification history of any users crontab.

Yes, I know that crontabs are in /var/spool/cron. I know that the date/time of the users file is the last time they modified.

But, I don't know if there's any way to find out when previous modifications have been made. (any log of additions or deletions?).

Also been searching the /var/cron/log but that only seems to have the commands executed from the crontab, but not whether the crontab was replaced with a new version.

Someone mentioned to me that the user.au file might have some clues.. but, I can't tell what the format of that file is, so, it's not much help to me right now.


If there's no built-in method for tracking these changes vis Solaris.... then what options would you guys think are best for us to implement some type of backup of previous crontab versions (maybe keep 5-10 versions as backups, and just keep deleting the 11th old file as new versions are pushed into the cron).


Thanks!

I used to modify crontabs by listing crontab contents (-l option) and sending it to a dated file, this way i keep a record of the previous crontabs... if you use -e option for editing directly the crontabs, you can create an alias for "crontab -e" redirecting it to an script wich first store the previos version (crontab -l >filename) then give you the editor)...
Hope this could help...!

This is the only method I can think of. You can use the root cron to list user's crontabs and output them to a dated file.

However, if you want to know something that was in a cron before doing this. You might be out of luck.
