command to see current cron'ned jobs?

Morning.

I know quite a few locations for cron exist. /var/spool/cron, /etc/crontab, /etc/cron.d/* and et al.

Is there a simple command to list the currently recognized crons that are loaded? Such as this pseudo code:

Code:

cron --list-all-jobs

So i don't have to hunt down all the crazy locations and look through every .cron file?

Code:

crontab -l

?

no.

do this for proof, or a better view into what i mean.

Code:

echo "10 * * * * /bin/echo" >> /etc/cron.d/mynew.cron

then

Code:

crontab -l

See how that doesnt list all the active crons on your system?

something like:

Code:

# for i in /var/spool/cron/*; do echo ${i##*/}; sed 's/^//' $i; echo; done | grep -v "#"

?

Thank you. There are plenty of ways to do it with a script or oneliner.

I was interested to know if there was already a utility, as there always seems to be, to automatically tell us all of the things that are cronned from all the different places.
