Viewing all cron jobs

Periodically I run into the situation where I’m trying to find a cron job on a particular machine, but I can’t remember which user owns it. At least on CentOS, it’s easy:

cat /var/spool/cron/* will show all crons. The crontab command doesn’t seem to support doing this. The downside is that that command just mashes them all into one list, which is only useful if you don’t care who the job runs as. Usually I do. Here’s a simple little script to format the output a little bit:

for i in `ls /var/spool/cron/`; do
        echo "Viewing crons for $i"
        echo "--------------------------------------"
        cat /var/spool/cron/$i
