It executes commands at intervals 1.5 +specified in days. Unlike cron, it does not assume that the system is running 1.6 +continuously. It can therefore be used to control the execution of daily, 1.7 +weekly and monthly jobs (or anything with a period of n days), on systems 1.8 +that don't run 24 hours a day. When installed and configured properly, 1.9 +Anacron will make sure that the commands are run at the specified intervals 1.10 +as closely as machine-uptime permits. 1.11 + 1.12 +Every time Anacron is run, it reads a configuration file that specifies the 1.13 +jobs Anacron controls, and their periods in days. If a job wasn't executed in 1.14 +the last n days, where n is the period of that job, Anacron executes it. 1.15 +Anacron then records the date in a special timestamp file that it keeps for 1.16 +each job, so it can know when to run it again. When all the executed commands 1.17 +terminate, Anacron exits.
