1 Anacron is a periodic command scheduler. It executes commands at intervals
2 specified in days. Unlike cron, it does not assume that the system is running
3 continuously. It can therefore be used to control the execution of daily,
4 weekly and monthly jobs (or anything with a period of n days), on systems
5 that don't run 24 hours a day. When installed and configured properly,
6 Anacron will make sure that the commands are run at the specified intervals
7 as closely as machine-uptime permits.
9 Every time Anacron is run, it reads a configuration file that specifies the
10 jobs Anacron controls, and their periods in days. If a job wasn't executed in
11 the last n days, where n is the period of that job, Anacron executes it.
12 Anacron then records the date in a special timestamp file that it keeps for
13 each job, so it can know when to run it again. When all the executed commands
14 terminate, Anacron exits.
