When to use this schedule
The canonical nightly job: date rollovers, daily aggregates, log rotation, cleanup of yesterday's temporary files. @daily and @midnight are accepted synonyms on most implementations.
What to watch out for
Midnight is the single most contended minute on any server, because it is everyone's default. If several jobs share the host, stagger them — 7 0 * * *, 23 0 * * * and so on. There is also a subtler problem: a job that processes "today" at 00:00 is processing a day that has barely started. Daily aggregation jobs almost always want to process yesterday, which makes them naturally idempotent and safe to re-run.
The crontab line
0 0 * * * /usr/local/bin/your-job.sh >> /var/log/your-job.log 2>&1Redirect the output somewhere you will actually read it — by default cron mails it, and on a host with no mail transport that means it is discarded. See the crontab guide for the surrounding syntax.
