Does Greenstone 2.83 automatically add chron tasks?

[Christian Pietsch]

Hi John,

I have not used Greenstone before, but it is possible that software
packages add cron jobs, e.g. as a post-install script that is run
automatically.

This does sound like a cron job, but you may not have found all of
them. Unfortunately, there are many places to consider ...

Cron jobs of user root:
$ sudo crontab -l
$ cat /etc/crontab  # and look there for more directories, e.g.:
$ ls -la /etc/cron.daily/
$ ls -la /etc/cron.weekly/
$ ls -la /etc/cron.monthly/
$ ls -la /etc/cron.d/

Cron jobs of user www-data (who runs Apache on Debian/Ubuntu):
$ sudo crontab -u www-data -l

There might me more cron jobs below /var/spool/cron, e.g.:
$ sudo ls -la /var/spool/cron/crontabs/


It's a mess, I know!
Cheers
Christian
